1/2 - 2/15= 15-4/30 = 11/30 this means that if you were to add 11/30 to 2/15 is exactly equal to 1/2, to fully answer your question you can use any value above that like 12/30 (keep in mind you have to simplify) = 6/15 = 2/5. But then again your question says to add any number to make it greater than 1/2 so technically you could just add 100 or 200 or 1/2 to make the sum of it greater than one half

How to find A? help please and thanks

MrRa [10]

This problem exercises the concept of "similar triangles."

With similar triangles, we can compare the sides using ratios.
The equation we can use to find side A is stated below.

Side 1A / Side 1B = Side 2A / Side 2B

The number refers to the triangle, and the letter refers to the side of each triangle. Side A in both triangles must be the base of the triangle, and side B in both triangles can be either of the other sides. The only restriction is that once we pick a side B on triangle 1, we must pick that same side on triangle 2.

A / 7 = 3 / 2

Then we can solve for the length of side A.

A = 7*3/2 = 21/2 = (E) None of These
