Line p is parallel to side BC.

Triangle A B C. Angle A is 2, angle B is 73 degrees, and angle C is 37 degrees. A line p is parallel to side B C at point A to form 3 angles. Angle 2 is angle A, and angle 1 is the exterior angle.

What is the measure of angle 1 in degrees?

73 degrees

Step-by-step explanation:

The interior angle equals to 180. 73+37+ m<2 = 180. That means angle 2 is 70 degrees.

m<1 and m<C and equal due to alternate interior angles. That means angle 1 is 37 degrees.

We know angles 1 and 2 equal to 37 and 73. That means the angles are equal to the interior triangle. 70+37= 107.      180-107= 73 Degrees

simple put is 73°
