Please show a pic so i can understand better
Complimentary angles will add up to 90 degrees
x + y = 90
x = 2y
2y + y = 90
3y = 90
y = 90/3
y = 30......this is one angle
x = 2y
x = 2(30)
x = 60.....this is ur other angle
and ur larger angle is 60 degrees
I hope this helps you
-20-(4x-1)=-15
-20-4x+1=-15
-20+1+15=4x
-4=4x
x=-1
