Q:
# WILL MARK AS BRAINIEST!!!!!!! In this triangle, which of the following is true?

Accepted Solution

A:

Answer:DStep-by-step explanation:The sum of the 3 angles in a triangle = 180°Subtract the sum of the 2 given angles from 180x = 180° - (90 + 35)° = 180° - 125° = 55°----------------------------------------------------------Since the triangle is right use the cosine ratio to solve for bcos35° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{b}{20}[/tex]Multiply both sides by 2020 × cos35° = b, henceb = 16.38 ( to 2 dec. places )
