Answer 2

Answer: The measure of angle y will be 45 degrees.

Step-by-step explanation:

In the given figure, line 'm' and 'l' form a set of parallel lines with the transversal 't' passing through them.

Thus, the angles y and 135° are a pair of interior angles on the same side of a transversal.

It is the property of interior angles on same side of transversal that their sum is equal to 180°.

Hence, we can write

∠y + 135° = 180°

or ∠y = 180°-135°

or, ∠y = 45°
