Question

if an angle is twice its twice its supplement what is the measure of that angle​

Answer 1

When the sum of two angles equals 180 degrees, they are referred to as supplementary angles,which forms a linear angle together.

Let us consider one supplement angle = X

Twice of supplement angle = 2X

X + 2X =180°

3X =180°

X = 180° /3

X = 60°

Supplement = 2 × 60°

∴ Supplement = 120°
