Answer:
Step-by-step explanation:
The marked sides tell you the triangle is isosceles. The marked angles tell you the segment AD is a bisector of the apex angle, so is perpendicular to the base BC. That means angle x° is 90°.
∠DAC is then the complement of 47°, and y° is equal to that, so is ...
y° = 90° -47°
y° = 43°
