I HOPE THIS WILL HELP YOU
Step-by-step explanation:
Two Angles are Supplementary when they add up to 180 degrees.
When two angles add to 90°, we say they "Complement" each other.
If α is the angle, 3 times it’s complement is 3(90 - α)
It’s supplement is 180 - α
3( 90 - α) = 120 -α
270 -3α = 120 - a
Answer:- a= 75
