The measure of the angle Y in given triangle is 120 º.

Step-by-step explanation:

Here, in ΔXYZ

∠X = 34 º , ∠Z = 26 º

By, ANGLE SUM PROPERTY of a Triangle:

Sum of all the interior angles in any given triangle is always 180 º.

⇒ ∠X+ ∠Y + ∠Z = 180 º

or, 34 º + ∠Y + 26 º = 180 º

or, ∠Y = 180 º - 60 º

⇒ ∠Y = 120 º

Hence, the measure of the angle Y in given triangle is 120 º.
