tweo supplementary angles are in ratios of 5:7 find the measures of the angles

Ratio - 5:7
5:7 = 180 degrees ( as the sum of two supplementary angles is 180 degrees )
5x + 7x = 180
12x = 180
x = 180/12
x = 15
Now, let the two angles be:
Angle 1 and Angle2
So,
Angle 1 = 15*5 = 75 degrees
Angle 2 = 15*7 = 105 degrees

For confirmation ,
105 + 75 = 180
Because when two supplementary angles are added (here, 105 degree and 75 degree angles)
Their sum will always be 180 degrees as shown above.
Thumbs up!!!
