Question

in the adjoining figure, if A is parallel to B then value of y is? ​

Answer 1

Answer:

yes this is right way to draw it

Answer 2

Given: In the adjoining figure, A is parallel to B.

To find: The value of y.

Solution:

Let the slanting line be C, the point of intersection of A and C be O and the point of intersection of B and C be P. ∠CPB is y and is corresponding to ∠COA. As evident from the figure, 120° and ∠COA are supplementary. So, ∠COA can be calculated as,

180° - 120° = 60°

Since ∠COA and ∠CPB are corresponding, they're equal. Hence, ∠CPB is also 60°.

Therefore, the value of y is 60°.
