Answer: I believe 14.1 should be correct
Explanation:
Given that we know one side length is 52 and the other is 21, we can use these values to create a scale.
52/21 = 2.4761, so we know that all sides will decrease by a scale of this value.
Given that, we can find the length of the MN. 35/2.4761 = 14.135
The question asks to round to the nearest tenth, so the answer should be 14.1. hope this helps!
