Answer:
22.6°
Step-by-step explanation:
Reference angle = <FDE
Side opposite to <FDE = 5
Hypotenuse = 13
The trigonometric ratios to apply is:
![sin(\theta) = \frac{opp}{hyp}](https://tex.z-dn.net/?f=%20sin%28%5Ctheta%29%20%3D%20%5Cfrac%7Bopp%7D%7Bhyp%7D%20)
Plug in the values
![sin(\angle FDE) = \frac{5}{13}](https://tex.z-dn.net/?f=%20sin%28%5Cangle%20FDE%29%20%3D%20%5Cfrac%7B5%7D%7B13%7D%20)
![sin(\angle FDE) = 0.3846](https://tex.z-dn.net/?f=%20sin%28%5Cangle%20FDE%29%20%3D%200.3846%20)
![\angle FDE = sin^{-1}(0.3846)](https://tex.z-dn.net/?f=%20%5Cangle%20FDE%20%3D%20sin%5E%7B-1%7D%280.3846%29%20)
(nearest tenth)
P=pages and H=hours, I’m assuming she read 20 pages, so C. h=20p should be correct, sorry if it wrong tho :)
