Question

pls tell the answer​

Answer 1

angle a+angle b+angle c=180°{Linea pair}

50°+90°+angle c=180°

140° + angle c=180°

angle c=180°-140°

angle c=40°

angle c=angle f=40°{vertically opposite angles}

angle a =angle d=50°{vertically opposite angles}

angle b=angle e={vertically opposite angles}

Answer 2

Answer:

Angles a=angle d =50 (vertically opposite angles)

angle b=angle e =90(vertically opposite angles)

therefore,

angle d+angle e+angle f=180

90+50+angle f=180

140+angle f=180

angle f=180-140

angle f=40

Therefore

angle f =angle c=40(vertically opposite angles)

Answers are -

angle c=40

angle f =40

angle d=50

angle e=90

Very easy sum! ☺
