From the given triangle diagram figure, angles are -

m∠1 = 72°

m∠2 = 114°

m∠3 = 66°

m∠4 = 66°

m∠5 = 56°

m∠6 = 32°

Depending on how many sides a polygon has, it is given a unique name. Because "tri" is a word that indicates "three," the polygon with three sides is known as a triangle. This polygon has three angles, as indicated by its name. Poly means numerous in the prefix.

Three vertices make up a triangle, a three-sided polygon. The triangle's angles are formed at a point where the three sides are joined end to end. The triangle's three angles add up to a total of 180 degrees.

In the given problem,

m∠6 = 180° - (90° + 58°)

so, m∠6 = 32°

Next, m∠1 +m∠6  = 180° - (42° +34°)

                             = 104°

so, m∠1 = 104° - 32°

             = 72°

Next, m∠5 = 90° - 34°

m∠5 = 56°

Again, m∠4 = 180° - (56° + 58°)

m∠4 = 66°

Now from the figure, m∠3 and m∠4 are vertically opposite angle.

So, m∠3 = 66°

Again, m∠2 = 180° - 66° = 114°

Step-by-step explanation:

(.65)^4 x (0.35)

By saying that he makes a free throw on the fifth show, he did not make the first four, therefore 4 of the times he shot, he did not get it in.

If he makes the shot 35% of the time, he doesn't make it 65% of the time: (1-0.35=.65)

On the last shot he made it, which he makes 35% of the time therefore:

You want to multiply : 0.35 (which is = 35%) by itself four times and then multiply that by 0.65 (since the last shot was made)

0.35 x 0.35 x 0.35 x 0.35 x 0.65 = 0.009754 or 0.9754%

There is a 0.9754% chance he makes it BUT a 0.009754 probability

Answer:

The midpoint of a line segment is the point that is exactly halfway between the two endpoints of the line segment. If the coordinates of one endpoint are (x1, y1) and the coordinates of the other endpoint are (x2, y2), then the coordinates of the midpoint are given by:

M = ((x1 + x2)/2, (y1 + y2)/2)

In this case, the coordinates of the midpoint are (4, 0), and the coordinates of AA are (3, -1). Therefore, the coordinates of BB must be (5, 1).

You can confirm this by calculating the midpoint using the coordinates of AA and BB:

M = ((3 + 5)/2, (-1 + 1)/2)

= (4, 0)

This shows that the point (5, 1) is indeed the other endpoint of the line segment, and the coordinates of BB are (5, 1).

Answer:

X=8, y=19

Step-by-step explanation:

These two triangles are congruent. This means that angle STR = angle MNL, so angle STR = 63°. We know the angles in a triangle must sum to 180°, so we can figure out 3x from this, given that we know the other two angles. 63 + 93 = 156, so 3x = 180-156=24. This gives us that x = 8. Now we can solve for x, because we know that SR = ML, so 3x + y = 43. We know x = 8, so we get that 24 + y = 43, or y = 19.

Answer:

(- 4, 2 )

Step-by-step explanation:

x + 5y = 6 → (1)

x + 3y = 2 → (2)

subtract (2) from (1) term by term to eliminate x

(x - x) + (5y - 3y) = 6 - 2

0 + 2y = 4

2y = 4 ( divide both sides by 2 )

y = 2

substitute y = 2 into either of the 2 equations and solve for x

substituting into (1)

x + 5(2) = 6

x + 10 = 6 ( subtract 10 from both sides )

x = - 4

solution is (- 4, 2 )

In linear equation, plant b height will exceed the height of plant a after 16 days.

What in mathematics is a linear equation?

A linear equation is a first-order (linear) term plus a constant in the algebraic form y=mx+b, where m is the slope and b is the y-intercept.        

                                  Sometimes, the aforementioned is referred to as a "linear equation of two variables," where x and y are the variables.

Plant a: 5 cm tall and rate of change = 2.5 cm per month

Plant b: 4  cm tall and rate of change = 4.5 cm per month.

Now we have to form the linear equations.

Plant a:

y = 2.5x + 5, where y is the total height and "x" be the number of months.

Plant b:

y = 4.5x + 4 , where y is the total height and "x" be the number of months.

Now we have to when the height of the plant a and plant b are the same.

To do that, we have to equivate both the equations and find x.

2.5x + 5 =4. 5x + 4

Isolate the variables terms and constants.

4.5x - 2.5x = 5 - 4

2x = 1

Dividing both sides by 2, we get

x = 1 ÷ 2

x = 0.5 months.

So after 15 days, the height of the plant a and plant b are the same.

Therefore, plant b height will exceed the height of plant a after 16 days.

Answer:

Step-by-step explanation:

The rate of change is the slope of the line formed by connecting the two data points:

1.  (2010,1510). and   [enrollment for a school in 2010 was 1510 students]

2.  (2020, 860)         [In 2020, the enrollment was 860 students]

Slope is the Rise/Run of the line.  Lets go from the first point to the second.

The Rise:  (1510 - 860) = 650

The Run:   (2020-2010) = 10

The slope, or rate of change, is = 65

The interpretation is that "The enrollment at the school increase by an average of 65 students every year since 2010 until 2020."

Addition, Distributive, Addition, Multiplication, Division

Step-by-step explanation:

The required function f(x) is represented by -1 + F(x + sin(x)).

To find the function f(x), you can use the formula for integration by substitution:

f(x) = F(g(x)) + C

where F is an antiderivative of f, g is a function such that g'(x) = f(x), and C is a constant.

In this case, we can take g(x) = x + sin(x). Then g'(x) = cos(x), so f(x) = F(g(x)) + C = F(x + sin(x)) + C.

We are given that f'(π) = 2 and f(π) = -1, so we can use these values to find the constants C and F.

First, we can find F by taking the derivative of F(x + sin(x)). This gives us:

F'(x + sin(x)) = f(x) = cos(x)

Substituting x = π and using the fact that F'(x + sin(x)) = f'(π) = 2, we get:

F'(π + sin(π)) = 2

Since sin(π) = 0, this simplifies to:

F'(π) = 2

Then, using the fact that F(x + sin(x)) = f(π) = -1 when x = π, we can find the value of F(π):

F(π) = -1

Now that we have found the values of F and F', we can use these to find the value of C.

Since F(x + sin(x)) = F(x) + F'(x) sin(x), we can substitute x = π to get:

F(π + sin(π)) = F(π) + F'(π) * sin(π)

Substituting the values we found above, this becomes:

F(π + 0) = -1 + 2 x 0

Which simplifies to:

F(π) = -1

Since F(π) = -1, we can conclude that C = -1.

Therefore, the function f(x) is given by:

f(x) = F(x + sin(x)) + C = F(x + sin(x)) - 1

= -1 + F(x + sin(x))

Answer:  the solution to the system of equations is x = 12 and y = 16.

Step-by-step explanation: To solve this system of equations, you can use the method of substitution.

First, solve one of the equations for one of the variables. For example, you can solve the first equation for x:

2x + y = 40

2x = 40 - y

x = (40 - y)/2

Then, substitute this expression for x in the second equation:

x - 2y = -20

(40 - y)/2 - 2y = -20

Multiplying both sides by 2, we get:

40 - y - 4y = -40

-5y = -80

y = 16

Substituting this value for y in the first equation, we can solve for x:

2x + 16 = 40

2x = 24

x = 12

Therefore, the solution to the system of equations is x = 12 and y = 16.
