Answer:
X=98°
Step-by-step explanation:
53° + 45° = 98
98-180= 82
every triangle is always equal o 180°
so... 53°+ 45°+ 82° = 180
to find x you need to subtract 82 from 180 which is 98
<em>remember its important to find the inner degree before the outer.</em>
A = 31 degree
Cos 31 degree = 400/x
X = 400/ Cos 31
= 400/0.8572
= 466.7ft
