Question

Someone please me out

Answer 1

3.6

Explanation:

For the 20-deg angle, x is the opposite leg, and 10 cm is the adjacent leg. The trig ratio that relates the opposite leg to the adjacent leg is the tangent.

`\tan A = (opp)/(adj)`

`\tan 20^\circ = (x)/(10~cm)`

`x = (10~cm)\tan 20^\circ`

`x = 3.6~cm`
