Question

part 1 of 2
find the values of x and y.

x = (simplify your answer.)

Explanation:

Step1: Use the property of congruent triangles (SAS)

Since \(AB = BC\), \(AD = DC\), and \(BD\) is common. By \(SAS\) (Side - Angle - Side) congruence criterion, \(\triangle ABD\cong\triangle CBD\). So \(x = 57^{\circ}\).

Answer:

\(x = 57\)
