Answer:
<P 40, <Q 25, <PRQ 115, <PRS 65
Step-by-step explanation:
exteririor angle = sum of remote angles
(3x + 4) + (2x + 1) = (6x - 7)
3x + 2x + 4 + 1 = 6x - 7
5x + 5 = 6x - 7
+7 +7
5x + 12 = 6x
-5x -5x
12 = x
x = 12
find angle mesures:
3(12) + 4
36 + 4
40
2(12) + 1
24 + 1
25
6(12) - 7
72 - 7
65
forms linear pair
65 + m<PRQ = 180
-65 -65
m<PRQ = 115
