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^@
