Question #af17e

Answer 1

`45^@`

Explanation:

Let's call that angle `theta`.

Complimentary angles are when 2 angles sum up to `90^@`.
`=theta+"complimentary angle"= 90^@`
`="complimentary Angle" = 90-theta`

Supplementary angles are when 2 angles sum up to `180^@`
`=theta+"supplementary angle"= 180^@`
`="supplementary Angle" = 180-theta`

According to the que,

`180-theta=3(90-theta)`
`180-theta=270-3theta`
`-theta+3theta=270-180`
`2theta=90`
`theta= 90/2=45^@`
