In a triangle ABC, angle A = 50 degrees, angle B = 30 degrees Question: Find the degree measure of angle C.

In triangle ABC it is known:

Angle A = 50 °;
Angle B = 30 °;
Find the third corner C.

Solution:

The sum of all angles in a triangle is 180 °. If 2 angles are known in a triangle, then we can find the third angle, that is, angle C.

In order to find the angle C, you need to subtract 2 known angles from 180 °. That is, we get:

Angle С = 180 ° – 50 ° – 30 ° = 180 ° – 30 ° – 50 ° = 150 ° – 50 ° = 100 °;

As a result, we got that the angle C of the triangle ABC is equal to 100 °.
