Lines g, h, and l are parallel and m ∠ 1 = 52°. What is m ∠ 11?

2 answers:

6 0

M∠1 and m∠4 are equal because they are vertical.
m∠4 and m∠ 8 are equal because they are corresponding.
m∠8 and m∠12 are equal because they are corresponding.
m∠12 and m∠11 are supplementary, so the m∠11 must be equal to 128 degrees.

What is the factored form of n^3+512 (please answer) picture provided

Rama09 [41]

${n}^{3} + 512 \\ = {(n)}^{3} + {(8)}^{3} \\ by \: using \: {a}^{3} + {b}^{3} = (a + b)( {a}^{2} - ab + {b}^{2}) we \: \: \: get \\ = (n + 8)( {(n)}^{2} - n \times 8 + {(8)}^{2} ) \\ = (n + 8)( {n}^{2} - 8n + 64)$
