All you need to do for this is 155-75 which would be 80 :) hope this helps
First set up the equation (sum of the angles is 180)
2x + 2(x-1) + (5x +2) = 180
distribute:
2x + 2x -2 + 5x +2 = 180
combine like terms:
9x = 180
solve for x:
x = 20
SO:
2x° = 2(20) = 40 degrees
2(x-1)° = 2(20) - 2 = 40 - 2 = 38 degrees
5x + 2°= 5(20) + 2 = 100 + 2=102 degrees
check: 40 + 38 + 102 = 180
Answer:
1:3
Step-by-step explanation:
3 divide 3 1
9 divide 3 3
Answer:
I believe the answer is p over 5, it won't let me type it out but it put the p on top of the 5
