Question

angle x and angle y are supplementary angles. Angle y measures 139 degrees.
what is the measure of angle X?

Answer 1

Answer:

the sum of supplementary angles = 180

x+y=180

x+139=180

x=180-139

x=41

Answer 2

Answer:

sum of supplementary angles=180

if one angle measures 139

the other one is 180-139=41
