Question

Find x on the triangle

Answer 1

The answer is C hope it helps :))))

Answer 2

Answer:

(c)

Step-by-step explanation:

Using the cosine ratio in the right triangle

cos42°  = $\frac{adjacent}{hypotenuse}$ = $\frac{x}{12}$

Multiply both sides by 12

12 × cos42° = x, hence

x ≈ 8.9 → (c)
