Question

find the value of x,y,z in each of the following figure if l is parallel to m and a is parallel to b.​

Answer 1

Answer:

2x + 90 + x = 180°

3x = 180°-90°

3x = 90°

x =30°

2y = x

alternate interior angle

2y = 30°

y = 15°

2y + z = 180°

2(15°)+z=180°

z = 180-30

=150°

Answer 2

Answer:

x=30 ,y =15,z=150

Step-by-step explanation:

x+2x+90=180

3x+90=180

3x=180-90

3x= 90

x=90÷3

x=30

find Y

2y=30 (v.o.a)

y=30÷2=15

find z

2y+z=180

2(15)+z=180

30+z=180

z=180-30

y=150
