The measure of central angle ycz is 80 degrees. circle c is shown. line segments x c, w c, y c, and z c are radii. the length of x c is 9. angle y c z is 80 degrees. sectors x c w and y c z are shaded. what is the sum of the areas of the two shaded sectors? 18 units2 36 units2 45 units2 81 units2

The sum of the areas of the two shaded sectors is

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

The area of a circle is equal to

where

r is the radius of the circle

in this problem we have

substitute

Remember that

subtends the complete circle of area equal to

so

By proportion

Find the area of the two shaded sectors

understand that i don't know the answers

will someone answer his question

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
