Question

Solve the triangle.

B = 72°, b = 12, c = 8

Cannot be solved

C = 39.3°, A = 68.7°, a ≈ 16.5

C = 39.3°, A = 68.7°, a ≈ 11.8

C = 44.5°, A = 63.7°, a ≈ 11.8

Answer 1

Same deal here. Do the exact thing you just did.

Answer 2

So to solve this, we will use the law of sines. Have you been taught that?

Answer 3

not really

Answer 4

Draw out the triangle like last question.

Answer 5

Okay well law of sines is:

Where the capital letters are the angles and the lowercases are the side lengths.
