(15+13)/2 = 28/2= 14 years old
Answer: X=15 , Y=15
Step-by-step explanation:
This triangle is a 30, 60, 90 so that means it would be - a, 2a, a
on each side, so add that all together and you get x-15 and y-15
1. Add 4 to both sides of the equation.


2. Multiply 6/5.

x=
There are an infinite number of 3 number sets that will equal 9000, unless your looking for whole numbers.
If you want to find a set of whole numbers, first break 9000 into its factors:
5 * 5 * 5 * 3 * 3 * 2 * 2 * 2 = 9000
Now to find a set of 3 numbers, just combine some of the factors.
For example:
(5 * 5 * 5) * (3 * 3) * (2 * 2 * 2) = 9000
125 * 9 * 8 = 9000
Answer: y=2
3y+2=6y-4
6=3y
y=2
