Answer:
x= 51.3
x=35.1
Explanation:
10.)
For this one we have the adjacent side and the hypotonouse
Which means we'll use CAH
cos(x)=25/40
x= 51.31781255
(assuming that we have to round to the nearest tenth again)
x=51.3
12.)
For this one we have the adjacent and hyptonouse
we'll use CAH again
cos(x)=27/33
x= 35.09680123
x=35.1
