the angles must add to 180, so the missing angle is 55°, since
50+75+55 = 180
Determine the measure of each exterior angle.
The triangle looks like an upside down A with one line running longer at the point. The inside angles are A- 50 and in the next corner 75. In the bottom of the A-letter I need to solve for C and A and the extra line at the top of A-Letter is angle B
The measure of angle A is____ °.
The measure of angle B is____ °.
The measure of angle C is____ °.
