Question

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

Answer 1

y = 12.3 cm

Explanation:

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

cos35° =
`(adjacent)/(hypotenuse)` =
`(y)/(15)`

Multiply both sides by 15

15 × cos35° = y, hence

y ≈ 12.3

Answer 2

12.3

Explanation:

cos(35) = y/15

y = 15 * cos(35) = 12.3
