Answer:

1. B)
x \approx 12.8

2. A)
x \approx 3.9

Explanation:

1) Apply the trigonometric ratio tangent.


\tan(\theta) = \frac{\text{opposite}}{\text{adjacent}}

↓ plugging in the given values


\tan(58\textdegree)=(x)/(8)

↓ multiplying both sides by 8 to isolate x


8\tan(58\textdegree) = x

↓ plugging the left side into a calculator

B)
x \approx 12.8

2) Apply the trigonometric ratio sine.


\tan(\theta) = \frac{\text{opposite}}{\text{hypotenuse}}

↓ plugging in the given values


\sin(34\textdegree) = (x)/(7)

↓ multiplying both sides by 7 to isolate x


7\sin(34\textdegree) = x

↓ plugging the left side into a calculator

A)
x \approx 3.9
