Question

I f the difference between two supplementary angles is 80 degrees then the larger of the two angles is


please give me answer ​

Answer 1

Answer:

Let The angles be x and y

x-y=80

=x=80+y ---------eq(1)

Since angles are supplementary ,

x+y=180

=80+y+y=180 --------from eq(1)

=80+2y=180

=2y=180-80

=2y=100

=y=100/2

=y =50

Then putting y=50 in eq(1),

x=80+50

=x=130

Thus, the larger angle is 130°
