Question

Use the Law of Sines to solve for the variable. Round your answer to the

nearest whole number. Write the value only. *

Answer 1

y ≈ 61

Explanation:

Using the Sine rule in the triangle

`(y)/(sin117)` =
`(21)/(sin18)` ( cross- multiply )

y × sin18° = 21 × sin117° ( divide both sides by sin18° )

y =
`(21sin117)/(sin18)` ≈ 61 ( to the nearest whole number )
