Theo was asked to find the measure of x in the following polygon. A polygon has angles 63 degrees, 63 degrees, x, and x. Theo’s work is shown below. Steps Theo’s Work Step 1 (n minus 2) 180 degrees = (4 minus 2) 180 degrees Step 2 2 (180 degrees) = 360 degrees Step 3 63 degrees + 63 degrees + x degrees = 360 degrees x = 234 degrees Where, if at all, did Theo first make a mistake finding the measure of x? step 1 step 2 step 3 Theo did not make a mistake.
