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?

Answer:

it is 80 degrees for first and then 105 degrees for second

Step-by-step explanation:

The measure of ∠BAC is 105°.

Given that, ∠DAC=(x-20)°=25° and ∠DAB=(2x-10)°.

What are adjacent angles?

The two angles are said to be adjacent angles when they share the common vertex and side.

Now, ∠DAC=(x-20)°=25°

⇒x=45°

So, ∠DAB=(2x-10)°=80°

Then ∠BAC=∠DAC+∠DAB=25°+80°=105°

Therefore, the measure of ∠BAC is 105°.
