Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = 5x + 1
x = 2
x = 3
<u>Step 2: Evaluate</u>
x = 2
- Substitute: f(2) = 5(2) + 1
- Multiply: f(2) = 10 + 1
- Add: f(2) = 11
x = 3
- Substitute: f(3) = 5(3) + 1
- Multiply: f(3) = 15 + 1
- Add: f(3) = 16

Answer:
x = 40°
Step-by-step explanation:
Reference angle = x°
Adjacent side length to reference angle = 7.2
Hypotenuse = 9.4
Apply trigonometric function CAH, which is:
Cos x = Adj/Hyp
Substitute
Cos x = 7.2/9.4
Cos x = 0.76596
![x = cos^{-1}(0.76596)](https://tex.z-dn.net/?f=%20x%20%3D%20cos%5E%7B-1%7D%280.76596%29%20)
x = 40° (nearest tenth)
