Question

Determine the length of x in the triangle. Give your answer to two decimal places. most importantly show the steps, please.

Answer 1

x=43.85

Explanation:

solution Given.

let the given angle be θ: 20 degree.

It's opposite side is 12.

It's hypotenuse is x.

Since

We have

Sin θ= opposite/hypotenuse

Sin20 degree=12/x

0.34202014332=12/x

doing criss cross multiplication

x=12/0.34202014332

therefore x=43.8570660032

in two decimal form x=43.85
