Question

An angle is twice of its
complement, find the angels
​

Answer 1

let the angle be x

from the condition

x+ 2x = 90

3x= 90

x= 90/3

x= 30°

the angle = 2x =2×30=60

hope that it will help you

Answer 2

let the angle be x

the it's complement angle = 2x

so

$x + 2x = 90$

$3x = 90$

$x = \frac{90}{3}$

$x = 30$

answer is 30
