Step-by-step explanation:

for a

  • a+,38°=90°{ angle at circumference through center is 90°}
  • a=90-38
  • a=52°

for e

  • e=38°{base angle of isosceles triangle r equal}

for d

  • 38°+e+d=180°{sum of angle of triangle}
  • d=180-76
  • d=104°

for. c

  • c+d=180°{straight angle}
  • c=180-104°
  • c=76°

for b

  • a+b+c=180°{sum of angle of triangle}
  • b=180-128
  • b=52°

hope it helps.

stay safe healthy and happy.
