Answer:
A = 50 - 10 = 40
B = 50
C = 50 + 20 = 70
Step-by-step explanation:
Given:
Perimeter (A + B + C) = 160cm
A = B - 10cm
B = A + 10cm
C = B + 20cm
Try to find B first:
A + B + C = 160
B - 10 + B + B + 20 = 160 | Substitute for the variables
3B - 10 + 20 = 160
3B + 10 = 160
3B = 160 - 10
3B = 150 | Divide both sides by 3
B = 50
Hoped that helped! :D
