#2 part b. the equation is 100+3x+2x=180 and part c. is 3x=48 and 2x=32
I think this is the answer. i havent done any math for a while.
Answer:When an angle is its own supplement, that means that the angle, plus itself, will equal 180 degrees.
Step-by-step explanation:
X+y=155. Y= -x+155
1.50x +4(-x+155)= 520
1.50x-4x+620=520
-2.5x =-100
X= 40. Y=110
