Two isosceles Triangles have equal vertical angles and their areas are in the ratio 9:25. Find the ratio of their corresponding heights .	Choose the correct option.
A) 4 / 5
B) 5 / 4
C) 3 / 2
D) 5 / 7
E) 3 / 5

Rationale: "we are basically given that the triangles are similar . in two similar triangles , the ratio of their areas is the square of the ratio of their sides and also , the square of the ratio of their corresponding heights . therefore , area / area = height ^ 2 / height ^ 2 = 9 / 25 - - > height / height = 3 / 5 . answer : e ."
Answer: E
