Question

Please help me!?

Part 1: Make up an angle measure for angle C and a length for one of the sides (AB, BC, or CA).

Part 2: Use a trigonometric ratio (sine, cosine, or tangent) to solve for one of the other side lengths.

For full credit, please provide both the ratio and work used to solve for the missing side length. Round your solution to the nearest hundredth.

Answer 1

So would it be 3.30 ? I would have to divide 65/20 which is 3.25 and then round it and get 3.30?

Answer 2

65/sin(20)

Answer 3

71.2?

Answer 4

So 22.23??
