Step-by-step explanation:
Answer:
The smaller angle = 31°
The larger angle = 149°
Step-by-step explanation:
The sum of two supplementary angles = 180 degrees
Lets x = the smaller angle
larger angle = 5x - 6
So now you have the equation:
x + 5x - 6 = 180
6x - 6 = 180
6x = 186
x = 31
The smaller angle = 31 degrees
The larger angle = 5(31) - 6 = 149 degrees
