In triangle ABC, angle A = 50 degrees and angle B = 30 degrees, calculate the degree measure of angle C.

In triangle ABC it is known:

Angle A = 50 °;

Angle B = 30 °.

Let’s find the angle C in degrees of the triangle ABC.

It is known that the sum of all the angles of a triangle is 180 °.

Also known are the 2 angles of the triangle ABC. Find the third angle C. To do this, subtract 2 known angles from 180 °.

Angle C = 180 ° – Angle A – Angle B = 180 ° – 50 ° – 30 ° = 180 ° – (50 ° + 30 °) = 180 ° – 80 ° = 100 °.

This means that the angle is C = 100 °.
