Answer 2

Answer:

Angle Z = 40° and Angle Y = 100°

Step-by-step explanation:

In triangle XYZ, it is given that XY = YZ.

So, XYZ is an isosceles triangle.

We know that in an isosceles triangle, the angles opposite to equal sides are also equal.

So, angle X = angle Z

Angle Z = 40° (as angle X = 40°)

Now, using angle sum property of a triangle,

Angle X + Angle Z + Angle Y = 180°

40°+40°+Angle Y = 180°

Angle Y = 180°-80°

Angle Y = 100°
