What is a supplementary angle??
Olin [163]
A single angle is generally not considered to be supplementary. Supplementary angles are angles that equal 180° when they are added together. For example, 70° and 110° are supplementary because they equal 180°.

However, I guess the supplementary angle can be the angle that must be added to another to total 180°. For example, 80° is the supplementary angle of 100°.

How would the expression x^3+64 be rewritten using sum off cubes
Mamont248 [21]
\bf \textit{difference of cubes}
\\ \quad \\
a^3+b^3 = (a+b)(a^2-ab+b^2)\qquad
(a+b)(a^2-ab+b^2)= a^3+b^3 \\ \quad \\
a^3-b^3 = (a-b)(a^2+ab+b^2)\qquad
(a-b)(a^2+ab+b^2)= a^3-b^3\\\\
-------------------------------\\\\
\boxed{64=4^3}\qquad x^3+64\implies x^3+4^3\implies (x+4)(x^2-x4+4^2)
\\\\\\
(x+4)(x^2-4x+16)

What is 1 4th of 10 explain
Nat2105 [25]
I have seen you ask this question twice before, so I will give you the answer that HugoD gave you:

In mathematics, "of" is translated as a multiplication.

So, you have : \frac{1}{4} * 10 =  \frac{10}{4} =  2, 5.
