I want answer in question no 28 80 will equal to angle b

Answer 2

Step-by-step explanation:

Let angle x = 80°

then angle x = b .......{ these are vertically opposite angles}

and, angle x = c ......{ these are corresponding angles}

Since, angle x + a = 180° ....{ linear plane }

a = 180°- angle x

a = 180° - 80°

a = 100°

Now, a = d ..... { these are alternate angles}

Hence, we got

a = 100°

b = 80°

c = 80°

d = 100°
