B) 8
Step-by-step explanation:
Because the triangles are similar, we can use a proportion to solve this.
11/6=33/3x-6
cross multiply
11(3x-6)=33*6
distribute and multiply
33x-66=198
add 66 on both sides
33x=264
divide 33 on both sides
x=8
-22
times both sides by 2, times () by 8, add alile terms, move terms, add alike and caculate divide both sides by 3
