Question

Guys i need these answers badly so i would appreciate if someone responded
Thanks !

Answer 1

Y is the midpoint of XZ, so XY = YZ

• 20x - 30 = 12x + 10
• 20x - 12x = 10 + 30
• 8x = 40
• x = 5

Find XZ:

• XZ = 2(XY) = 2(20*5 - 30) = 140

The answer is:

• x = 5 and XZ = 140

------------------------

B is the midpoint of AC, so AB = BC

• 4x + 3 = 2x + 15
• 4x - 2x = 15 - 3
• 2x = 12
• x = 6

Find AC:

• AC = 2(AB) = 2(4*6 + 3) = 54

The answer is:

• x = 6, AC = 54
