The measure of its supplementary angle is 42 degrees
The sum of supplementary angle is qual to 180 degrees
Let the required angle be x
The sum of the supplements of 138 degrees will be expressed as:
x + 138 = 180
x= 180 - 138
x = 42 degrees
Hence the measure of its supplementary angle is 42 degrees

5 is an integer but 2/3 is not an integer
1/2 × b × h = A
1/2 × b × 10 = 100
5b = 100
b = 100/5
b = 20
