Answer:
x = 24
Step-by-step explanation:
These are similar triangles, which means that their sides have the same ratios.
Since the bottom of the large triangle is 15, and the bottom of the small triangle is 17, that means that the ratio of large to small is - 1:3.
So, by multiplying the sides of the small triangle by 3, you get the side of the large triangle.
8 x 3 = 24
So, x must equal 24!
