I'll be glad to check your answer.
An angle measures 148° less than the measure of its supplementary angle. What is the measure of each angle?
To find the supplementary angle of an angle, you need to subtract the given angle from 180 degrees, as supplementary angles add up to 180 degrees.
In this case, to find the supplementary angle of 148.7 degrees, you can use the following calculation:
Supplementary angle = 180 - 148.7
Therefore, the supplementary angle of 148.7 degrees is 31.3 degrees.
