Question

Solve each triangle. Round your answers to the nearest tenth.

Answer 1

The best I can do is provide with the equation. Sine= opposite over hypotenuse. Cosine= adjacent over hypotnuse and tangent = opposite over adjacent.

Answer 2

Explanation:

You can use law of sin and law of cos to solve for this triangle because this is not a right triangle

Law of Cosine

b² = a² + c² − 2ac cos (B)

b² = 26² + 13² - 2(26)(13) cos 88

b² = 821.41

b= 28.66

AC=28.66

Now use Law of Sin to find angles:

`(sin B)/(b) = (sin C)/(c)`

`(sin 88)/(28.66) = (sin C)/(13)`

`13(sin 88)/(28.66) = sin C`

sin C = .4533

C = 26.96

A = 180-C-B

A= 180-88-26.96

A= 65.04
