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

hello from mrbilldoesmath!

answer:

(7 x + 6 y) (49 x^2 - 42 x y + 36 y^2)

discussion:

the trick is to recognize that 343 = 7^3 and 216 = 6^3 and, in general,

a^3 + b^3 =   (a + b) (a^2 - a b + b^2).

in our case

343x^3+216y^3   =   (7x)^3 + (6y)^3

so take a = 7x and b = 6y in the above equation to get the answer.
