Triangle a has a height of 2.5 cm and a base of 1.6 cm. the height and base of triangle b are proportional to the height and base of triangle a. which of the following could be the height and base of triangle b? choose 3 answers: a. height: 2.75 base: 1.76b. height: 9.25 base: 9.16c. height: 3.2    base: 5d. height: 1.25 base: 0.8e. height: 2      base: 1.28

A, D, E

Step-by-step explanation:

The ratio height : base is ...

... 2.5 : 1.6

... = 25 : 16

... = 1.5625 : 1

You can eliminate the bogus answers B and C because ...

... B: the numbers are too close together. The larger would need to be near 13 for the smaller one to be 9.

... C: the base is larger than the height, so the ratio is less than 1, not greater than 1.
