Not entirely sure if this is the right answer but angles BAC and ACD are the same because they are alternate angles. You can tell because of the parallel lines AB and CD they lie on. That could probably be how the triangles are congruent because they have the same angles... I’m just guessing

Inessa [10]

Answer:

m∠P  = 65°

Step-by-step explanation:

An Isosceles triangle has two sides of equal length and two interior angles of equal measure.

Sum of interior angles of a triangle = 180°

If QO ≅ PQ and the enclosed m∠Q = 50° then m∠P ≅ m∠O

⇒ m∠Q + m∠P + m∠O = 180

⇒ 50 + m∠P + m∠O = 180

⇒ m∠P + m∠O = 130

As m∠P ≅ m∠O:

⇒ m∠P  = 130 ÷ 2 = 65°
