It wont let me post a picture of the angles but they are verticle angles and the equations are (3x+8), (5x-40) and it says find m abc.

the choices are 24, 56, 80, 90

]supplementary angles are two angles that add up to . • complementary angles are two angles that add up to degrees. • adjacent angles share a and a • congruent angles have the measure. • an triangle has one angle that is greater than 90 degrees. • a triangle with angles 45°, 45°, and 90° would be a triangle
