Question

hi how to solve this..​

Answer 1

Answer:

we know that circle measure is 360°

d) is given a Right angle.

i.e: d=90

Arc AMB is 180°

Angle DMB is given 20°.

Therefore,

AMB=AMP+PMD+DMB

180°=90°+c+20°

c = 70°

Angle DMB = Angle AMC.... opposite angle

Therefore, a =20°

angle AMB= Angle AMC +Angle CMB

180°= 20° + b

b=160°

I hope you get it
