Question

Angle=a and angle=b are supplimentary angles. If angle=b is 5 times angle =a find the measure of both the angles.

Answer 1

Sum of supplementary angles=180°

Angle=b is 5 times angle=a

So, sum of angle b and angle a = (5+1) or 6 times angle a = 180°

∴ Angle a = (180÷6)° = 30°

  Angle b = (30×5)° = 150°

Ans: The value of Angle a is 30° and the value of Angle b is 150°.
