Also this one please and explain how you solved it... Thank you guys

x = 85/3

Step-by-step explanation:

Here, we want to find the value of x

As we can see , we have two similar triangles here

The small one at the top and the bigger one that encompasses the whole shape

When two triangles are similar, the ratio of their corresponding sides are equal

Thus, we have it that;

12/20 = 17/x = 15/25

12/20 = 17/x

12 * x = 17 * 20

12x = 340

x = 340/12

x = 170/6 = 85/3
