Answer:
x = 29°
Explanation:
we have two isosceles triangles, two sides and two congruent angles, the sum of the internal angles of a triangle is 180°, we solve the triangle on the right, remove 64° from 180° and divide by 2 to find the congruent angles (180-64): 2=58°.
Now we pass to the left triangle, which has a consecutive angle with the right triangle, therefore 180°-58=118, now we find the congruent angles of which one is "X", (180° - 122):2= 29° ( your answer)
