Step-by-step explanation:
a)<PTR=90°(angles in a semicircle)
<RPT=50°
<PRT + <PTR + <RPT=180°(angles in a triangle)
<PRT=180-(90+50)
<PRT=40°
b)From ∆QTS
<TQS = <RTP =50°
<QTS=180-(50+28)
<QTS=102°
c)<QTR=180-(90+50)
<QTR=40°

Answer:
d = 10
Step-by-step explanation:
50 + 2 ( 2 - d ) = 3 ( 1 + d ) + 1
50 + 4 - 2d = 3 + 3d + 1
54 - 2d = 4 + 3d
- 4 -4
50 - 2d = 3d
+2d +2d
50 = 5d
50/5
d = 10
