Question

6. Find XY.

Help ASAP

Answer 1

Answer:

mXY = 21

Step-by-step explanation:

mWX and mXY must add up to mWY

Step 1: Set up equation

mWX + mXY = mWY

a + (a + 6) = 36

Step 2: Solve for a

1. Combine like terms:               2a + 6 = 36
2. Subtract 6 on both sides:      2a = 30
3. Divide 2 on both sides:          a = 15

Step 3: Find mXY

mXY = a + 6

mXY = 15 + 6

mXY = 21
