To find the missing measure of an angle in a triangle if you know the measure of two of the interior angles, you should:

• Subtract the sum of the two known angles from 180 degrees.

• Add the two known angles together.

• Multiply the two known angles.

• Divide 180 degrees by the sum of the two known angles.
