Ответ:
You can just add 100 as the denominator.
Ответ:
the missing side is , c= 22.1 and the missing angles are , ∠a= 36.7° and ∠b= 53.2° to the nearest tenth.
in the triangle abc, ∠c = 90°
the side opposite to ∠a is, a= 13.2 and side opposite to ∠b is, b= 17.7
according to the pythagorean theorem:
⇒ c = 22.1 (taking square root on both sides)
for finding the missing angles, we will use the sine rule of triangle.
according to the sine rule:
so the missing side is , c= 22.1 and the missing angles are , ∠a= 36.7° and ∠b= 53.2° to the nearest tenth.
