If two angles of a triangle are complementary, it means they add up to 90 degrees. Since the sum of the angles in a triangle is always 180 degrees, the third angle would be 180 degrees minus 90 degrees, which equals 90 degrees. Therefore, the measure of the third angle in this triangle would be 90 degrees.
70 degrees
Yes a 90- 60-30 triangle for example because there are 180 degrees in a triangle.
The third angle is 75 degrees. The 3 angles of a triangle add up to 180 degrees. Therefore: 45 + 60 + 75 = 180.
If two angles of a triangle each measure 45 degrees, the third angle measures 90 degrees. This is because of the Triangle Sum Theorem - The sum of the measure of the interior angles of a triangle is 180 degrees. If you know that two of the angles total to be 90 degrees, you can subtract that 90 degrees from the total 180. The result is 90 degrees.
