Question

find the measure of an angle that is double its supplement

Answer 1

Let the first angle be x and second amgle be 2x

Measure of supplementary angles is 180°



A/q,


x + 2x = 180°

3x = 180°

x = $\frac{180}{3}$

x = 60


1st angle => x => 60°

2nd angle => 2x => 2 × 60 => 120°

Answer 2

$\bold{Hay\:Mate}$


let the first angle x and second angel 2x

now,

ㄥx + ㄥ2x = 180°

ㄥ3x = 180°

$x = \frac{180}{3}$

x = 60


so, angle x = 60°, angle 2x => 2×60 = 120°


I hope it's help you
