In the figure below, AD and BE are diameters of circle P. What is the arc measure of CAD in degrees?

the arc measure of CAD in degrees is 296

Step-by-step explanation:

Angle EPA is 90 degrees. Since angle EPA and angle EPD are on a straight line, then

Angle EPD = 18 - 90 = 90 degrees

Angle EPD = 33k - 9

33k - 9 = 90

33k = 90 + 9 = 99

k = 99/33

k = 3

Angle CPD = 20k + 4 = (20 × 3) + 4

Angle CPD = 60 + 4 = 64 degrees

Since the sum of the angles at a point is 360 degrees, it means that

90 + 90 + angle BPC + 64 + 90 = 360

Angle BPC = 360 - 334

Angle BPC = 26 degrees

Therefore, the arc measure of CAD in degrees is

26 + 90 + 90 + 90 = 296 degrees

let's cover over the formula of the vertex:

y = a(x – h)^2 + k

in this formula, (h,k) are the vertex, always remember that the positive or negative value of the vertex is based on the sign it has.

for example, if the vertex is -3,-6 then both the x and y value would have the positive sign attached to it and if it were a positive x and y value, then a negative sign would be attached to it.

with that being said, for our problem the x value is a positive one so we are looking for a number with a negative sign next to it, in this case the first and second choice.

however, for the first answer choice it isn't quite part of the formula so we know that the answer choice correctly displays the x value.

to confirm, we can see if the -1 fits correctly with the second answer choice, and as mentioned above a negative number will have a positive sign attached to it. so, for our problem we can see that -1 has been changed to +1, so we can confirm that the second answer choice is correct.

hence, our final answer is y=(x - 1)^2 + 1

9987
