Question

hy

solve 28 no quickly!

Answer 1

PB parallel to CQ

so, 70 = 20 + y ( due to corresponding angles are equal)

y = 70 - 20

y = 50

BC = AC

So In triangle ABC,

A=B = 50

C= 180-(50+50)

 = 80

At angle C

80 + x + 70 = 180

150 + x = 180

x = 180 - 150

x = 30

So, option C is correct

Answer 2

Hello miss here is ur answer

So 70=20+y( due to corresponding angles are equal
y=70-20
y=50
In triangle ABC
A=B=50
C=180-(50+50)
C=180-100
C=80
A+angle C
80+X+70=180
150+X=180
X=180-150
X=30
here is ur solution hope it will help you a lot
