\(PQ = QR = PR\)
It will be an equilateral triangle so all the angles will be \(60\)
\(x = 180 - 60 = 120\)

If PQ = QR = PR, then triangle PQR is an equilateral triangle, which means each angle in the triangle is 60°.
Since angles on the line add to 180°, we can write: ∠QRP + x = 180
Since ∠QRP = 60°, our equation becomes: 60 + x = 180, which means x = 120.
Answer: E
