answer: the first one

step-by-step explanation: use a calculator and divide the minutes by the dollars.

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.

1/4 because there is 4 grades.

d. it is a convex pentagon because it has five sides and none of the sides would extend into the inside of the polygon.
