If the measure of arc CB is 8/3 units, what is the measure of CAB?
Oksanka [162]

Question:

If the measure of arc CB is \frac{8}{3} \pi units, what is the measure of ∠CAB?

Answer:

120°

Step-by-step explanation:

The figure has been attached to this response.

The figure shows a circle centered at A and has a radius of 4 units.

Also, the length of the arc CB (as given in the question) is  \frac{8}{3} \pi units.

The length <em>L </em>of an arc is given by;

L = \frac{\beta }{360} * 2\pi  * r         -----------------(i)

Where;

β = angle subtended by the arc at the center of the circle and measured in degrees

r = radius of the circle

From the question;

β = ∠CAB

r = 4 units

L =  \frac{8}{3} \pi

<em>Substitute these values into equation (i) as follows;</em>

\frac{8}{3} \pi = \frac{\beta }{360} * 2\pi  * 4

=>  \frac{8}{3} \pi = \frac{\beta }{360} * 8\pi

<em>Cancel 8</em>\pi<em> on both sides</em>    

\frac{1}{3} = \frac{\beta }{360}

<em>Cross multiply</em>

3 x β = 360 x 1

3β = 360

<em>Divide both sides by 3</em>

<em />\frac{3\beta }{3} = \frac{360}{3}<em />

β = 120°

Therefore, the measure of ∠CAB is 120°

Answer:

y = -63

Step-by-step explanation:

y - 15 = -78

Add 15 on both sides to get y alone:

y - 15 + 15 = -78 + 15

y = -63

The odds of selecting a red card from a box of cards are 2:5. What is the probability of not selecting a red card from a box?
Kipish [7]
3:5 because if there's a 2:5 chance of grabbing a red card then just subtract 2 from 5 and you get 3:5
