.
The sum of the angles in a triangle is 180 degrees.
.
angle A + angle B + angle C = 180 degrees
40 degrees + angle B + 55 degrees = 180 degrees
angle B = 85 degrees.
.
Knowing all the angles of triangle ABC and knowing
triangle XYZ is equal to ABC, the measure of angle Y
is the measure of the corresponding angle of ABC.
