Answer: XY=21 YZ=29
Step-by-step explanation: okay so the entire line (XZ) is equal to 50, and its made up of a and a + 8. So you can make an equation out of that.
a+a+8=50
2a+8=50
2a=42
a=21
then you just have XY equal 21, and YZ equal 21+8 or 29.
Answer:
XY = 21
YZ = 29
Step-by-step explanation:
XZ = 50
XY = a
YZ = a + 8
XY + YZ = XZ
a + (a + 8) = 50
2a + 8 = 50
2a = 50 - 8
2a = 42
a = 42 ÷ 2
= 21
