I believe x is equal to 16.5 degrees.

Angle OTA is 33 degrees, and each vector of the angle is tangent to the circle, which makes the arc length of the circle 33 degrees as well.

x is on the opposite side of the circle, and the vectors of its angle contain the same portion of the circle as angle OTA. Since the angle point is on the opposite side of the circle, the arc length is double that of the angle.

Simply divide 33 by 2 and presto: 16.5 degrees.

I hope this helps! :)

Which pair of angles are supplementary?

PolarNik [594]

Answer: H

Step-by-step explanation:

Supplementary angles just mean they add up to 180 degrees. 180 degrees means that when the two angles are put together one of each of their sides will form a straight line.

Suppose that you believe that contractor 1 is twice as likely to win as contractor 3 and that contractor 2 is three times as lik

Ray Of Light [21]

Answer:

probability that contractor 1,2 and 3 win is 33%,50% and 17% respectively

Step-by-step explanation:

assuming that there are no other contractors then:

probability that 1 , 2 or 3 win = 1

denoting as X= probability that contractor 3 wins , then assuming that only one wins , we have

probability that 1 , 2 or 3 win = 1

probability that contractor 1 wins + probability that contractor 2 wins + probability that contractor 3 wins = 1

2*P(X) + 3*P(X) + P(X) = 1

6*P(X) = 1

P(X) =1/6

then

-probability that contractor 1 wins = 2/6 (33%)

-probability that contractor 3 wins = 3/6 (50%)

-probability that contractor 3 wins = 1/6 (17%)

Please help!

Refer to the image attached.

Since, we have to divide the polynomial $4x^2-2x+3$ by (x+2) using synthetic division.

We will divide the coefficients 4 -2 3 by -2

First term = 4 will remain same.

Second term = $(-2 \times 4) -2 = -8-2 = -10$

So, second term = -10

Third term = $(-2 \times -10)+3 = 23$

So, third term = 23

So, 4 -10 23 is the correct answer

So, Option 2 is the correct answer.
