Question

PLEASE ANSWER!!! NEED HELP WITH EXPLANATION!!!

Answer 1

Answer:

27.37 and 9.18

Step-by-step explanation:

(4)

Using the cosine ratio in the right triangle

cos64° = $\frac{adjacent}{hypotenuse}$ = $\frac{12}{x}$ ( multiply both sides by x )

x × cos64° = 12 ( divide both sides by cos64° )

x = $\frac{12}{cos64}$ ≈ 27.37 ( to the nearest hundredth )

(5)

Using the sine ratio in the right triangle

sin35° = $\frac{opposite}{hypotenuse}$ = $\frac{x}{16}$ ( multiply both sides by 16 )

16 × sin35° = x , then

x ≈ 9.18 ( to the nearest hundredth )
