13/32=0.40625 that would be the answer to the problem
Base in your question the coordinate is P is 2, PQ has a coordinate of 8 while PR has a coordinate of 12. To find the mid point of each segment you must first find the coordinate of QR which is from 8-12. So the answer will be
PQ = 5, PR = 6, and QR= 10
<em>PQR = 150°</em>
- <em>Step-by-step explanation:</em>
<em>Hi there ! </em>
<em>PQR = PQS + SQR</em>
<em>12x - 6 = 16 + 9x + 17</em>
<em>12x - 9x = 16 + 17 + 6</em>
<em>3x = 39</em>
<em>x = 13</em>
<em>PQR = (12×13 - 6)° = (156 - 6)° = 150°</em>
<em>Good luck !</em>
