Question

The measures of two angles of a triangle are given below. Find the measure of the third angle of the triangle in decimal form. 22.8°, 65.3° The measure of the third angle is

Answer 1

We know that there are 180 degrees in a triangle. Therefore we can set up an equation with what we have:

22.8 + 65.3 + x = 180
88.1+x=180
x=91.9

The third angle is 91.9 degrees
