Question

I need answers with steps​

Answer 1

Answer:

x=40° , y=40° , z= 50°

Step-by-step explanation:

Given: L1,l2,l3 intersect at O

To find: x,y,z

Solution: z=50° (V.O.A)

t=90° (V.O.A)

Now, in line l3

t+ x+50=180° (Angles on straight line)

90°+x+50°=180°

x+140°=180°

x=180°-140°

x=40°

Now, y=40° (V.O.A)
