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?

Angle DAC = x − 20 = 25, so x = 45.
Then m∠DAB = 2x − 10 = 2(45) − 10 = 80°.
m∠BAC = m∠DAB + m∠DAC = 80° + 25° = 105°.
Then m∠DAB = 2x − 10 = 2(45) − 10 = 80°.
m∠BAC = m∠DAB + m∠DAC = 80° + 25° = 105°.
