M = angle x
N = angle x's supplement

M + N = 180
M = 82 + N

82 + N + N = 180
2N = 98
N = 49

M = 82 + 49 = 131

supplementary angles is composed of 2 angles that totalled 180degrees.if x is 82 degrees more than the other angle,we can make an equation...
let x=the 1st angle (the supplement)

x+82=the 2nd angle (the unknown)

the equation: (x)+(x+82)=180

solution: (x)+(x+82)=180
2x+82=180
2x=180-82
2x=98
2x/2=98/2
x=49 (this is the supplement angle)

substitute the value of x in x+82 to get the angle measure of angle x.....

angle x=49+82
=131degrees.................

let x be the first angle.
x + 82 is the second angle

supplementary angles are angles that add up to 180

x + x + 82 = 180
2x = 98
x = 49

x+x-82=180
2x-82=180
2x=262
x=131 degrees

x + y = 180
x = y + 82

x + y = y + 82 + y = 2y + 82 = 180

2y = 180 - 82

2y = 98

y = 49
