Question

find the value of x.
if necessary, you may learn what the markings on a figure indicate.

Explanation:

Step1: Use the property of congruent triangles

Since the two triangles are congruent (marked with equal sides), the angles opposite the equal sides are equal. The right - angled triangle has a total of \(90^{\circ}\).

Step2: Calculate the value of \(x\)

We know that \(x + 65^{\circ}=90^{\circ}\). Then \(x = 90^{\circ}-65^{\circ}\).

Answer:

\(25\)
