Question

This is due in a few hours. How do I solve the triangles missing side to the nearest tenth?​

Answer 1

Answer: 4.7

Explanation:

We are trying to find the opposite side from the angle and are given the adjacent side to the angle, so looking at SohCahToa we have (a) and need (o) so we would use tangent (tan)

tan(20) = o/a

tan(20) = x / 13, multiply 13 on both sides

13 * tan(20) = x

4.73161 = x, round to the nearest tenth and that is x = 4.7
