Answer:
11
Explanation:
As these triangles are similar, there is a common ratio between them. Let's set up fractions and solve for x.
It doesn't matter which way you set this up as long as you use the same method for each side of the triangle. I'm going to go from the smaller triangle to the larger triangle.
33/6x-11 = 36/60 Now cross multiply
33(60)=36(6x-11) Distribute
1980 = 216x - 396 Add 396
2376 = 216x Divide by 216
11 = x
