Question

Do the adjoining figure ine de la lineb
Line is the transversal .find the value
of y.​

Answer 1

Answer:

y = 50°

Step-by-step explanation:

Given, two lines are transversal.

y + 15 and it's adjacent angles are supplementary.

So, adjacent angle = 180-y-15

adjacent angle = 165-y

Since lines are transversal, 165-y and 2y+15 are equal.

165-y = 2y+15

-3y = -165+15

-3y = -150

y = 50°
