Question

Question is stated in picture. DONT FIRGET TO ROUND TO NEAREST HUNDRETH!!!!

Answer 1

In order to find the missing angle y we need to use a trigonometric function in this case the cosine because is the one that relates the adjacent side and the hypotenuse

`\cos (\theta)=(AS)/(H)`

where

θ=y

AS=8

H=13

then we substitute the values

`\cos (y)=(8)/(13)`

then we isolate the y

`y=\cos ^(-1)((8)/(13))`
`y=52.02\text{\degree}`
