Question

What is the measure of ∠D ?

Answer 1

To find angles you have to use an inverse function. Tan-1(25/45). your angle is 29.0546041 but rounded to the nearest hundredth it is 29.05.

Answer 2

To get angle D, we have to use tangent, but specifically the inverse of tangent. Tangent means opposite over adjacent so we do $tan^{-1} =25/45$ 

Therefore, angle D is 29.05 degrees.
