45°
in this triangle, the product of tan a and tan cis

answer:

tan a = tan c = tan 45

we can tell that tan is 1.

1*1 is 1.

the answer is simply just 6n add the two together as they have an n

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.

you,
