30°

Step-by-step explanation:

The area of a triangle given sides a and b and angle C is:

area = (ab × sin C)/2

Here we are given sides a and c, and we are looking for angle B, so we have

area = ac × sin B

12 cm² = [(8 cm)(6 cm)(sin B)]/2

24 = 48sin B

sin B = 0.5

B = 30°

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.

you,
