Answer:
Step-by-step explanation:
We assume Q is between P and R.
<u>According to segment addition postulate we have:</u>
<u>Substitute values and solve for x:</u>
- 7x - 3 + 32 -2x = 59
- 5x + 29 = 59
- 5x = 30
- x = 6
<u>Find PQ:</u>
- PQ = 7*6 - 3 = 42 - 3 = 39 units
<u>Find QR:</u>
- QR = 32 - 2*6 = 32 - 12 = 20 units
