Question

In the adjoining figure. line p || line q . line t is a transversal. If m angle a = ( x + 20 )° , m angle f = ( 2 x + 10 )° . find the value of ` x '​

Answer 1

Answer:

from the figure ....

angle A = angle C(vertically opp. angles)

and angle C = angle F(allied angles)

therefore,angle A= angla F

x + 20=2x + 10

x = 10......

Answer 2

Answer:

50

Step-by-step explanation:

angle a = angle c ( Verticaly opposite angle)

So, angle c = x + 20

p and q are parallel So, angle c + f = 180° ( co - interior )

x + 20 + ( 2 x + 10 ) = 180

3 x + 30 = 180

3x = 180 -30

x = 150/3

x= 50
