Answer:
Step-by-step explanation:
<u><em>( 8 ).</em></u> m∠1 = m∠ 4 = m∠ 5 = <em>m∠6 = 52°</em>
<em><u>( 9 ).</u></em> m∠ 2 = m∠ 3 = <em>m∠ 7</em> = m∠ 8 = 180° - 52° <em>= 128°</em>
We can see that, when the input is 5, the output is 24.

How to evaluate an equation?</h3>
Here we have the equation:
![y = x^2 - 1](https://tex.z-dn.net/?f=y%20%3D%20x%5E2%20-%201)
Where y is the output and x is the input.
We want to evaluate it with the input as 5, so we need to replace the variable x by the number 5, we will get:
![y = 5^2 - 1 = 24](https://tex.z-dn.net/?f=y%20%3D%205%5E2%20-%201%20%3D%2024)
Then we can see that, when the input is 5, the output is 24.

Answer:
Step-by-step explanation:
f(x) = 2x + 5
f(-6)= 2(-6) + 5 = -12 + 5 = -7
