Answer: This is a perfect square trinomial. You are trying to find the binomials that multiply to that. In order to do that, you do the following.

Multiply 2x^2 by 4 (A times C)

Find what numbers multiply to give you 8 and add to give you 7.

When you do this, you will notice that there are no numbers that do this. That makes your answer D. NONE OF THESE.

sin∅ = opposite over hypotenuse

Step-by-step explanation:

Step 1: Define

∅ = 40°

opposite leg of angle = 50 ft

hypotenuse = x ft

Step 2: Solve for x

Substitute: sin40° = 50/x
Multiply x on both sides: xsin40° = 50
Divide sin40° on both sides: x = 50/sin40°
Evaluate: x = 77.7862
Round: x = 77.8 ft
