These are two similar triangles. (a) Which proportion could be used to solve for x?

(b) Now, solve that proportion.

a) Either  or

b) x = 2.667

Step-by-step explanation:

Given - These are two similar triangles.

To find - (a) Which proportion could be used to solve for x?

                (b) Now, solve that proportion.

Solution -

Given that,

a.)

The triangle are similar , so corresponding sides proportion is equal

i.e.

So,

we can use any proportion for solving x

Either  or

b.)

Now,

If we take

∴ we get

x = 2.667

And

If we take

∴ we get

x = 2.667

So,

we have from both proportion

x = 2.667

i found two solutions,   n = 2 • ± √3 = ± 3.4641
