Find the measure of angle 2.

Step-by-step explanation:

see the attached figure with letters to better understand the problem

step 1

Find the measure of arc BC

we know that

----> by complete circle

substitute the given values

step 2

Find the measure of angle 2

we know that

The inscribed angle is half that of the arc it comprises.

so

substitute

e.

step-by-step explanation:

because there are always 10 numbers in a phone number.

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.
