Gezbe, let's recall the properties of an isosceles triangle:
1. It has at least two equal sides.
2. This property is equivalent to two angles of the triangle being equal.
Therefore, an isosceles triangle has both two equal sides and two equal angles.
Now, we know that angle y is also 42 degrees.
For calculating x, we use the following formula:
x = 180 - 42 - 42
x = 180 - 84
x = 96
Solution: x = 96 and y = 42
