In a triangle, one angle is 30 degrees and the other 40. Find the third angle.

Find the third corner of the triangle if 2 angles of the triangle are known. The first angle is 30 degrees and the second angle is 40 degrees.

In a triangle, the sum of all angles is 1802 degrees.

Let x be the third angle.

Let’s make an equation and find the third angle.

30 + 40 + x = 180;

70 + x = 180;

x = 180 – 70;

x = 100 + 80 – 70;

x = 100 + 10;

x = 110;

This means that the third angle is 110 degrees.
