Answer:-C. is the correct option."m∠P = m∠O"


Explanation:-

Let the measure of ∠O be x

Then ∠2= 2x ..........>Exterior angle of triangle

We know that for a triangle ,

Exterior angle= Sum of opposite interior angles

⇒∠2=∠O+∠P

⇒2x=x+∠P  [Substitute values of ∠O and ∠2]

⇒x=∠P   [Subtract x on both sides]

⇒∠P=∠O=x [Transitive property]

∴ C. is the correct option.

Answer:  -6, -3, -2, -1, 1, 2, 3, 6

<u>Step-by-step explanation:</u>

NOTES: p is the last term, q is the coefficient of the first term

Determine all of the factors of p and all of the factors of q

Possible rational roots are all of the combinations of p/q for every factor

\dfrac{p}{q}=\pm \dfrac{6}{1}=\pm \dfrac{1\times 6, 2\times 3}{1}=\pm\dfrac{1}{1}, \pm\dfrac{6}{1}, \pm\dfrac{2}{1}, \pm\dfrac{3}{1}\\\\\\\text{In order from smallest to largest:}\ \large\boxed{-6, -3, -2, -1, +1, +2, +3, +6}

A sheet of bad paper is cut into 12 equal parts. What percent of the whole is 3 parts?
11Alexandr11 [23.1K]
25%

Divide 12 by 3 and you'll get 4.
That means 1/4 or a quarter of the 12 is 3.
(Convert the fraction to its percentage form)
1/4 or 1 divided by 4 equals 0.25
Multiply 0.25 by 100 and you'll get 25%
