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.
