answer me this question of maths subject

Answer 1

If AB || CD and CD || EF then AB || EF || CD

Given:

y:z = 3:7

So let y be 3a and z be 7a,

So y+z=180°

So, 3a + 7a = 180°

10a = 180°

a = 18°

So y = 3a = 3*18 = 54°

and z = 7a = 7*18 = 126°

Now we know that x and y are linear pair.

So, x + y = 180°

x + 54° = 180°

x = 180° - 54°

x = 126°
