The measure of one supplementary angle is 45 degrees more than twice the measure of the other. write an equation to find the measure of each angle. solve to find each angle

Supplementary means they add up to 180°
x=2y+45
180= x+y
plug in
180= 2y+45+y
180=3y+45
-45 both sides
135=3y
÷3 both sides
45=y
solve for X
plug in
x=2 (45)+45x
x=90+45
x=135
y=45

Answer for 2: his profit would be $2.88 explanation: you have to first multiply 72 and 0.12 together to get $8.64 once you do that you know how much money the shopkeeper made from selling the candy bars individually. so you have to do 8.64-5.76=2.88 hope that ; )answer for 3: yeah i’m sorry i have no idea what number 3 is. i’m sorry i couldn’t with that.
