Answer:
x= 5; Segment QR is the mid segment and YW is the base of the triangle. Mid segments are half the length of the base.
Step-by-step explanation:
2x - 3 = (x + 9) ÷ 2 Multiply both sides by 2
(2x - 3) • 2 = x + 9
4x - 6 = x + 9 Add 6 to both sides
4x = x + 9 + 6
4x = x + 15 Subtract x from both sides
4x - x = 15
3x = 15 Divide 3 on both sides
x = 15/3
x = 5
