➷ cos38 = 79/x

x = 79/cos38

x = 100.2524

The correct option would be 100.25

Answer 2

Answer:

100.25

Step-by-step explanation:

Using the cosine ration in the right triangle, then

cos38° = $\frac{adjacent}{hypotenuse}$ = $\frac{79}{x}$

Multiply both sides by x

x × cos38° = 79 ( divide both sides by cos38° )

x = $\frac{79}{cos38}$ ≈ 100.25
