Applying the Angle Addition Postulate
In the diagram below, AngleDAB and AngleDAC are adjacent angles.
Lines A B, A D, and A C create two angle. The space between lines A B and A D is (2 x minus 10) degrees. The space between lines A D and A C is (x minus 20) degrees.
If mAngleDAC = 25°, what is mAngleDAB in degrees?
What is mAngleBAC in degrees?
