Question 1

TPV = 90 degree ( Angle in semicircle is a right angle)

PTZ = 90 degree (Angle in semicircle is a right angle)

WZP =  90 degree (Angle in semicircle is a right angle)

Others are right.

Question 2

EA = 90 degree

AB = BFD – AFE – EFD = 180 – 90 – 48 = 42 degree

BC = 48 ( vertically opposite angles )

DC = 90 + 42 = 132 ( As it is vertically opp. To BE , And BE = 90 + 42)

EDC = 90 degree (Angle in semicircle is a right angle)

AFC = 90 Degree

EFA = 90

DFC = 132

AFB = 42

EFD = 48

DCA = 90 (Angle in semicircle is a right angle)

EBD = 24

ACE = 45
