Find the length of y, assume the triangles are similar

y = 3.6

Step-by-step explanation:

Since the triangles are similar, we can write the following proportion:

We don't need the fraction on the left because it is not necessary to solve for y. Instead, we can simplify the rest:

Now, we can cross-multiply:

answer: '

the distance between points l and m

step-by-step explanation:

or

step-by-step explanation:

we need to solve for 'x' the following equation:  

we have that:
