Answer:
The answer to your question is: x° = 90° and y° = 43°
Step-by-step explanation:
Data
We conclude that the triangle is isosceles because 2 sides measure the same.
Also, because of the drawing, we observe that x° is a right triangle, so
x° = 90°.
Then, in isosceles triangles, ∠B = ∠C, and the sum of internal angles in a triangle equals 180°.
∠y + ∠B + ∠D = 180°
Substitution:
∠y + 47 + 90 = 180
∠y = 180 - 47 - 90
∠y = 43°
