I am stuck on this question and can’t go ahead without answering it :(

Angle 6 is equal to 60 degrees

Step-by-step explanation:

The answer is 60 degrees

Step-by-step explanation:

This is because <1 is 120, therefore <2 is 60 degrees.

Two angles on the same line are Complementary angles, so they must add up to 180 degrees.

180-120= 60.

Angle 6 is equal to angle 2, therefore <6= 60 degrees

I hope this helps :)

step-by-step explanation:

hello from mrbilldoesmath!

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

discussion:

in general, the factorization of a^3 + b^3 is

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

in our case note that 343 = 7^3 and 216 = 6^3 so the equation becomes:

343x^3 + 216y^3 = (7x)^3 + (6y)^3

if you think of a (above) as 7x and b as 6y the factorization becomes

343x^3 + 216y^3 =

((7x + 6y) (   (7x)^2 - 7x*6y + (6y)^2)   =

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