In Exercises 17 to 22, use a form of the Law of Sines to find the measure of the indicated side or angle. Angle measures should be found to the nearest degree and lengths of sides to the nearest tenth of a unit. To determine

To find:

The measure of a side in a given triangle, by using the law of sines.

Explanation

Concept:

The Law of Sines,

sinαa=sinβb=sinγc

Where α, β, and γ are the acute angles of the triangle, and a, b, and c are the sides of the triangle.

Calculation:

Given:

From the triangle

a=5ft

c=x ft,

β=65°

γ=70°

Find α:

For and triangle,

α+β+γ=180

Here, β=65 and γ=70

α+65+70=180

α+135=180

Add (135) on both sides,

α+135+(135)=180+(135)

α+135135=18013
