Question

solve for x and y

Explanation:

Step1: Use the property of isosceles triangles

In an isosceles triangle, the base angles are equal. Also, the sum of angles in a triangle is \(180^{\circ}\). For the upper triangle (where \(x\) is an angle), we know one angle is \(78^{\circ}\).

$$x + 78^{\circ}+78^{\circ}=180^{\circ}$$

$$x=180^{\circ}- 156^{\circ}$$

$$x = 24^{\circ}$$

Answer:

\(24^{\circ}\)
