Question

Each row contains the degree measures of two supplementary angles. Complete the table. On the table, type the correct answer in each box. measure of an angle measure of its supplement 80° 25° 119°

Answer 1

Supplementary angles have a sum of 180 degrees. So to find the supplement of an angle, simply subtract its measurement from 180.

180 - 80 = 100 degrees

180 - 25 = 155 degrees

180 - 119 = 61 degrees

180 - x degrees

The answers are: 100, 155, 61 and (180 - x) degrees.
