The measure of the missing angle is \( \square \) degrees. (Simplify your answer. Type a whole number or a decimal.)

In a triangle, the sum of all three interior angles always equals 180 degrees. So, if you know the measures of two angles, you can easily find the third angle by subtracting the sum of the known angles from 180. For example, if the two angles measure 30 degrees and 70 degrees, you would calculate 180 - (30 + 70) to get the missing angle, which would be 80 degrees. When solving for the missing angle, a common mistake is miscalculating the sum of the known angles or forgetting to subtract from 180. Double-check your addition, and make sure you’re working with degrees, not radians! Using a calculator can help, but make sure it’s set to degrees to avoid confusion while solving and ensuring your final answer is accurate.
