Answer 1

Answer:

x=5

Step-by-step explanation:

We can use proportions to solve this problem.  Put the side of the small triangle over the side of the large triangle.

9           15

------ = ----------

2x-1        3x

Using cross products

9*3x = 15(2x-1)

27x = 30x-15

Subtract 30x from each side

27x-30x = 30x-30x -15

-3x = -15

Divide by -3

-3x/-3 = -15x/-3

x = 5
