Question

please give me answer step by step.​

Answer 1

Answer:

y-40= z-90=x%z = x 40 figuring

Answer 2

step by step solution

x=40(alternate angles)

z+90+x=180 (angle sum property of a triangle)

z+90+40=180

z+130=180

z=180-130

z=50

now the agle beside x let it be angle 1

angle 1= z

1=50

y+40+50=180

y=180-90

y=90

or

we can also write y=90[angle opposite to equal side]
