A side of the triangle below has been extended to form an exterior angle of 133°. Find the value of x????????

Answer:

b > -3

Step-by-step explanation:

-5(2b+7) + b< -b - 11

Distribute -5

-10b - 35 + b < - b - 11

Combine like terms.

-9b - 35 < - b - 11

Add b to both sides.

-8b - 35 < -11

Add 35 to both sides.

-8b < 24

Divide by -8. REVERSE THE SYMBOL!! because dividing by a negative number.

b > -3

Answer:

x=3.42

Step-by-step explanation:

[tex] \sin(20) = \frac{x}{10} [/tex]

[tex]x = 10 \sin(20) = 3.42[/tex]

Answer:

x = 3.420 (to the nearest hundredth)

Step-by-step explanation:

Trig ratios:

sin(x) = O/H

cos(x) = A/H

tan(x) = O/A

where x is the angle, O = side opposite the angle, A = side adjacent to the angle, H = hypotenuse

We have been given:

angle = 20°

opposite side to angle = x

hypotenuse = 10

Therefore, we should use sin(x) = O/H

Substituting the above values into the trig ratio:

⇒  sin(20) = x/10

⇒  x = 10 sin(20)

⇒  x = 3.420 (to the nearest hundredth)

Answer:

x=15

Step-by-step explanation:

divide 20 by 8 and you get 2.5

multiply 2.5 by 6

Answer:

93

Step-by-step explanation:

The sum of the interior angles of a triangle is 180 degrees. The given measures, 37 and 56, sum up to 93. 180-93 = 87. This means the last interior angle is 87 degrees. But, the degree measure of a straight line is also 180 degrees, so 180-87 is 93, the answer.

Answer:

Addition Property of Equality

Step-by-step explanation:

Addition Property of Equality.

The addition property of equality justifies the work done in Line 3. This is because it essentially states that if you add something to one side of an equation, you must add it to the other side as well. In this case, we are adding 22 to both sides of the equation, therefore we are making use of the Addition Property of Equality.

Answer:

15200 cm²

Step-by-step explanation:

from inspection of the diagram, we can see that the prism comprises:

Triangle

Area of triangle = 1/2 x base x height

Given:

⇒ area = 1/2 x 60 x 40 = 1200 cm²

Base rectangle

Area of a rectangle = width x length

Given:

⇒ area = 60 x 80 = 4800 cm²

Side rectangle

Area of a rectangle = width x length

Given:

⇒ area = 50 x 80 = 4000 cm²

Total area = 2 triangles + base rectangle + 2 side rectangles

⇒ total area = (2 x 1200) + 4800 + (2 x 4000) = 15200 cm²

The right-angle triangle shows this condition. Then the value of angle x is 30.80°.

It is a type of triangle in which one angle is 90 degrees and it follows the Pythagoras theorem and we can use the trigonometry function.

The expression is given as

[tex]\rm x = \rm tan ^{-1} \dfrac{3.1}{5.2}[/tex].

We know that the tangent is the ratio of the perpendicular to the base of the right-angle triangle.

x will be the angle and the opposite side of the x will be the perpendicular of lengths 3.1 and 5.2 will be the base of the that is along the angle x.

The value of x is 30.80°.

Answer:

A. MO/SA = OE/AW

Step-by-step explanation:

A. would be your correct answer because if you analyze the triangles you can see that the similar sides would be MO and SA, OE and AW, and ME and SW. In all of the answers, they compare sides that arent similar like OE/SW. However, in the first answer, the sides they compare are indeed similar, as you can see by what I listed above. These sides are similar because they are both the adjacent and opposite sides of each triangle.

Answer:

  (a) 315°

  (b) 3°

  (c) 238°

Step-by-step explanation:

Bearings are measured clockwise from north. The triangle described is illustrated in the attachment.

The bearing of P from R is 180° different from the bearing of R from P it will be ...

  135° +180° = 315° . . . . bearing of P from R

__

The bearing of Q from R is 48° more than the bearing of P from R, so is ...

  315° +48° = 363°, or 3° . . . . bearing of Q from R

__

The angle QPR has a value that makes the sum of angles in the triangle equal to 180°. It is ...

  180° -48° -55° = 77°

The bearing of Q from P is 77° less than the bearing of R from P, so is ...

  135° -77° = 58°

As above, the reverse bearing from Q to P is ...

  58° +180° = 238° . . . . bearing of P from Q

Answer:

y = 6°

x = 19.4°

Step-by-step explanation:

Use alternating interior angles

The angle adjacent to 5x + 3 is equal to 58 because of alternating interior angles.

58+100+3y+4 = 162 + 3y

162 + 3y = 180

3y = 18

y = 6

The two base angles are equal because the two lines are parallel

5x + 3 = 100

5x = 97

x = 19.4

Answer:

y=2x+6

Step-by-step explanation:

Slope intercept form is:

y=mx+b

m: slope

b: y-intercept

We can start by solving for the slope. The equation for slope is:

[tex]Slope=\frac{y_2-y_1}{x_2-x_1}[/tex]

Plug in any two x, y pairs from the table into the equation. Let's use (-3, 0) and (0, 6):

[tex]Slope=\frac{6-0}{0-(-3)}=\frac{6}{0+3}=\frac{6}{3}=2[/tex]

y=2x+b

Now, we can plug in a x, y pair from the table in for x and y to solve for the y-intercept. Let's use (0, 6):

y=2x+b

6=2(0)+b

6=0+b

b=6

Therefore the equation is:

y=2x+6

The amount of money Candy started with after spending on drinks and cakes is £7.95

She bought a drink for £1.45 and a piece of cake for £1.20.

She has two thirds of here money left.

Let the money she has initially  = x

Therefore,

2 / 3 x = x - 1.45  - 1.20

2 / 3 x = x - 2.65

subtract x from both sides

2 / 3 x - x = - 2.65

2x - 3x / 3 = - 2.65

- x / 3 = - 2.65

cross multiply

-x = - 2.65 × 3

- x = -7.95

x = £ 7.95

Therefore, Candy started with £7.95

Given Equation :-

[tex]\qquad[/tex][tex] \pink{\bf \longrightarrow 5(p-3) = 63}[/tex]

We are asked to find the value of p in the above equation.

First multiply (p-3) by 5 –

[tex]\qquad[/tex][tex] \sf \longrightarrow 5 \times p - 5 \times 3 = 63[/tex]

[tex]\qquad[/tex][tex] \sf \longrightarrow 5p - 15 = 63[/tex]

The organization of the numbers in the triangles would look like this from top to bottom and from right to left: 2, 8, 4, 9, 3, 5, 7, 6, 1.

To organize the numbers we must take into account the final result that the sections highlighted in color, green, red and yellow, must add.

A key to being able to organize the numbers correctly was taking into account that the largest numbers could not be in the same section because they would add up to more than the required final number, 22.

According to the above, the distribution of the numbers was carried out in the following way and all the results coincide:
