Answer:
∠K'=37°
∠L'=43°
∠M'=100°
Explanation:
Given:
The triangle KLM is reflected over the y-axis and translated 3 units up.
To find the angles of a triangle K'L'M':
We know that reflection and translation transformation do not affect the angles of the triangle.
So, the angles are,
∠K'=37°
∠L'=43°
∠M'=100°
