Answer:
50 degrees =0.873 radian
Formula 50 degrees x π/180= 0.8727 radians
Area of the triangle = (1/2)*base*height
For right triangle base and height can be legs.
We have one leg = 5 ft. (Lets think it is a base.)
We need to find the other leg.
We are going to use Pythagorean theorem.
5² + b²=13²
b²=144
b=12 (It is going to be our height.)
Area of the triangle = (1/2)*5*12= 30 ft²
Area of the triangle = 30 ft²
The answer is B, d=8.75h
It’s 8.75h because Michael earns 8.75 per hour the key word is “per hour”
