Question

in the given figure a b parallel CD and l is transversal then calculate the value of x

Answer 1

i had solve this
finally x is 26

Answer 2

Answer:

x = 26

Step-by-step explanation:

In the given figure, AB || CD, line 'l' is the transversal.

we have,

3x + 35 = y    ( vertically opposite angles)

3x - y = -35   eq 1

Also, alternate angle to 'y' is also 'y' only.

2x + 15 + y = 180   ( linear pair angles)

2x +y = 165  eq 2

Add ing eq 1 & eq 2

5x = 130

x = 130/5 = 26

x = 26
