Question

How can you find the measure of the third angle of a triangle if the other two measures are known?

Answer 1

you would add up both of the other two measures and then subtract that by 180 since all triangles add up to 180 degrees

Answer 2

Answer : If you add all three interior angle measures together in a triangle it will always equal 180°.. To find a third angle you will subtract the sum of the two given angles from 180°
