Question

Lines and Angles
solve fast. i, ii and iii​

Answer 1

1st answer

As AB||CD then draw PQ which is also || to AB and CD bisecting angle x into two parts.

diagram refers to the attachment..

So , here x = x1 + x2

x1 = co interior angle of 104°

Sum of co interior angles is 180°

x1 = 180 - 104

x1 = 76°

Now x2 = co interior angle of 116°

x2 = 180°-116°

x2 = 64°

Adding both

x = 140°

2nd answer

Similarly here also draw PQ|| to AB and CD .

So angle x will divided into two parts.

Here x1 = alternate angle of 35°

So, x1 = 35°

and x2 = alternate angle of 65°

So x2 = 65°

Then x = 35+ 65

x = 100 °

3rd answer

Here also draw PQ|| to AB and CD .

So x1 = co interior angle of 35°

x1 = 180- 35

x1 = 145°

x2 = co interior angle of 75°

x2 = 180-75

x2 = 105°

x = 145 + 105

x = 250°

hope it helps
