Question

In ΔUVW, u = 5.8 inches, ∠W=77° and ∠U=87°. Find the length of v, to the nearest 10th of an inch.

Answer 1

1.6

Explanation

You can use the angles given to figure out the degree of the angles given and then with that you set up your equation as v divided by Sin(16) is equal to 5.8 divided by sin(87) and cross multiply.

After you cross multiply you should get approximately 1.5987 is equal to v times sin(87)

you then fin out the approximation of sin(87) which should be around 0.9986 and divide both sides by 0.9986 so v is alone and your answer comes out to be v = 1.6
