Answer:
20.99 m
Step-by-step explanation:
The apex angle is ...
180° -2·37.57° = 104.86°
By the law of sines, the unknown side x has length ...
x/sin(37.57°) = 33.28/sin(104.86°) = (side opposite)/sin(angle)
x = 33.28·sin(37.57°)/sin(104.86°) ≈ 20.99396 ≈ 20.99 . . . . meters
That is a difference of two square numbers, we can factorize them easily:
<span>0 =-b^2 + 25
b^2 - 25 = 0
(b + 5)(b - 5) = 0</span>
