Consider three orthogonal triangles (see picture)
1. The smallest triangle
2. The medium triangle
3. The big triangle that holds both triangles.
All are orthogonal (or right triangles) so you can use Pythagoras Theorem:
"The area of the square whose side is the hypotenuse is equal to the sum of the areas of the squares on the other two sides"
Use Pythagoras theorem on triangle 1.
[tex]a^{2} = 3^{2} + 6^{2} = 45[/tex]
Now user Pythagoras on triangle 2.
[tex]b^{2} = x^{2} + 6^{2} = x^{2} + 36[/tex]
Now use Pythagoras on triangle 3 (the big triangle).
[tex](3 + x )^{2} = a^{2} + b^{2}\\x^{2} + 6x + 9 = a^{2} + b^{2}[/tex]
Now replace the values for [tex]a^{2}[/tex] and [tex]b^{2}[/tex] from the two equations derived from triangle 1 and 2:
[tex]x^{2} + 6x + 9 = 45 + x^{2} + 36[/tex]
The two [tex]x^{2}[/tex] get cancelled out, so:
[tex]6x + 9 = 45 + 36\\x = 12[/tex]

Solve the question below, please
Answer:
b = 26.62
Step-by-step explanation:
You are given 2 sides and one angle. So the best option is to use cosine law.
[tex]b^{2} = a^2 + c^2 - (2ac)cos[/tex]θ
[tex]b^{2} = 26^2 + 11^2 - (2*26*11)cos30[/tex]
[tex]b^{2} = 708.77[/tex]
[tex]b = 26.62[/tex]
Find the midpoint of the segment with the following end points (10,5) and (6,9)
Answer:
The mid-point between the endpoints (10,5) and (6,9) is:
[tex]\left(x,\:y\right)=\left(8,\:7\right)[/tex]Step-by-step explanation:
Let (x, y) be the mid-point
Given the points
(10,5)(6,9)Using the formula to find the mid-point between the endpoints (10,5) and (6,9)
[tex]\left(x,\:y\right)=\left(\frac{x_2+x_1}{2},\:\:\frac{y_2+y_1}{2}\right)[/tex]
Here:
[tex]\left(x_1,\:y_1\right)=\left(10,\:5\right),\:\left(x_2,\:y_2\right)=\left(6,\:9\right)[/tex]
Thus,
[tex]\left(x,\:y\right)=\left(\frac{x_2+x_1}{2},\:\:\frac{y_2+y_1}{2}\right)[/tex]
[tex]\left(x,\:y\right)=\left(\frac{6+10}{2},\:\frac{9+5}{2}\right)[/tex]
[tex]\left(x,\:y\right)=\left(8,\:7\right)[/tex]
Therefore, the mid-point between the endpoints (10,5) and (6,9) is:
[tex]\left(x,\:y\right)=\left(8,\:7\right)[/tex]Reflection over the x axis ;vertical shift down 7 units

Keyshawn has a gift card with a $150 balance. He buys several video games that cost $35 each. After the purchases, his gift card balance is $45. Write an equation to help find out how many video games Keyshawn bought.
Answer:
what specifically are you asking how you would justify? Are you asking how to justify the original equation? If so, how much you spend + your new balance = original balance. Consider if you spent x dollars, your new balance is 10 dollars and your original balance was 15 dollars. Then x + 10 = 15 which means you spent x= 15 - 10 = 5 dollars. With this problem he spent 35 dollars per game so the total he spent is 35x. Since his new balance is 45 and his original balance was 150, then 35x + 45 = 150

Determine the value of y.
Question 9 options:
A) 45°
B) 27°
C) 24°
D) 135°
Answer:135
Step-by-step explanation:all you have to do is to multiply 45 2 times and you will get the answer
Since y is 27, the value of angle 5y will be 135°.
What are supplementary angles?Supplementary angles are those angles that sum up to 180 degrees.
Given 5y and 45° angles are supplimentry angles
Two angles are called supplementary when their measures add up to 180 degrees.
Thus,
5y + 45 = 180
5y = 135
y = 27°
therefore, the value of angle 5y will be 135° since y is 27.

The shape of this particular section of the rollercoaster is a half of a circle. Center the circle at the origin and assume the highest point on this leg of a roller coaster is 30 feet above the ground.
1. Write the equation that models the height of the roller coaster.
a. Start by writing the equation of the circle. (Remember that the general form of a circle with the center at the origin is x^2 + y^2 = r^2
b. Now solve this equation for y. (Remember the roller coaster is above ground, so you are only interested in the positive root.
2. Graph the model of the roller coaster using the graphing calculator. Either sketch by hand or take a picture and paste the image below.
Answer:
Step-by-step explanation:
Part A
x^2 + y^2 = 30^2
I don't know if this is right or not. That would mean that the roller coaster has no clearance and at the lowest point, it would scrape the ground (although not enough to dig a hole).
Part B
y^2 = 900 - x^2
y = sqrt(900 - x^2)
Part C
The graph is actually y = - sqrt(900 - x^2)
That's the only model I can come up with
The wording of the question does not allow for the condition that you want. (0,0) is not the center of the graph the way they want it. See the second graph).
Perhaps it means graph15b. I can't really tell.

m<2 = 127°
✔️m<7 = 180° - 53° (consecutive exterior angles are supplematry)
m<7 = 127°
