Answer:
x = 4
y = 65
Explanation:
The little red marks on the sides near x and 4 mean that those sides are congruent.
x = 4
In a triangle, opposite angles of congruent sides are congruent.
Angle y and the other base angle are congruent. They both measure y.
The upper angle measures 50°.
The sum of the measures of the angles of a triangle is 180°
y + y + 50 = 180
2y = 130
y = 65
