Question

Please help me out please!!!!!!!! :)

Answer 1

Answer:

12.3

Step-by-step explanation:

cos(35) = y/15

y = 15 * cos(35) = 12.3

Answer 2

Answer:

y = 12.3 cm

Step-by-step explanation:

Since the triangle is right with hypotenuse 15, use the cosine ratio to solve for y, that is

cos35° = $\frac{adjacent}{hypotenuse}$ = $\frac{y}{15}$

Multiply both sides by 15

15 × cos35° = y, hence

y ≈ 12.3
