Question

Find the value of x in the following figure 1 parallel m.

(i) 45°
(ii) 60°
(iii) 90°
(iv)120°​

Answer 1

the correct answer is 60°

Answer 2

☞Question:-

Find the value of x in the following figure where l || m.

☞Answer :-

60°

☞Step-By-Step Explaination:-

Let the angle vertically opposite to the angle marked 120° in the given figure be a.

Therefore,

a = 120°(Vertically opposite angles)

a + x = 180° ( Co-interior angles as l || m and there's a transversal)

=> 120 + x = 180°

=> x = 180° - 120°

=> x = 60°

Hence, (ii) 60° is the correct answer.
