Answer:

hope answer is 30°or40°..........

Answer 2

See given,

z = 2y - 10......( 1 )

And

z - y = 20

z = 20 + y ...... ( 2 )

From ( 1 ) & ( 2 ) , we get

2y - 10 = 20 + y

2y - y = 20 + 10

y = 30

So

z = 20 + y = 20 + 30 = 50

Now 5t = 4x ( vertically opposite Angles) ..... ( 3 )

Also 5t = z + y = 50 + 30 = 80 ( exterior angle property)

As

5t = 80

t = 16

Also

4x = 5t = 80

x = 20

So

x + t = 20 + 16 = 36
