EXPLANATION
The measure of the
By applying this theorem we can get the value of the angle CAB as shown as follows:
180 - 90 - 42 = 48 degrees
Then, by the supplementary angles theorem, we can assevere that the sum of supplementary angles is equal to 180 degrees.
180 - 48 = 132 degrees
Hence, the value of the supplementary angle is 132 degrees.
