Answer:
<h2>The value of <em>x </em>is 71°.</h2>
Step-by-step explanation:
The given triangle has to equal sides, this means that the triangle isosceles, from which we can deduct from the theorem of isosceles triangles that<em> the angles formed by these two equal sides are congruent.</em>
Also, we know that the sum of all internal angles of a triangle must be 180°. So

Therefore, the value of <em>x </em>is 71°.
