Question

Can someone please help me with an explanation on how to find Y

Answer 1

y ≈ 8.63 cm

Explanation:

using the sine ratio in the right triangle

sin52° =
`(opposite)/(hypotenuse)` =
`(6.8)/(y)` ( multiply both sides by y )

y × sin52° = 6.8 ( divide both sides by sin52° )

y =
`(6.8)/(sin52)` ≈ 8.63 cm ( to 3 significant figures )
