Find two supplementary angles such that the measure of the first angle is 38° less than three times the measure of the second.

angle 1+ angle 2=180 supplementary angles add up to 180
angle 2=x assign angle a variable
angle 1= 3x-38 find equation for first angle
3x+x-38=180 set both angles added together equal to 180
4x-38=180 combine like terms
4x=218 add 38 to both sides
x=54.5 divide by 4
angle 2= 54.5
angle 2= (3x54.5)-38 plug back in and solve
**angle 1= 125.5 **

3x-38 x-2nd angle
3x-38+x=180 4x-38=180 4x=218 x=54.5
First angle 3(54.5)-38 163.5-38 125.5

The two supplementary angles are 54.5° and 125.5°. The first angle is calculated as 125.5°, which is 38° less than three times the second angle, 54.5°. Together, they sum to 180°.
