2. write a function that models the relationships among x, y, and r. (hint: use the pythagorean theorem.)
then solve the equation for rin terms of x and y.
(3 points: 1 point for the correct pythagorean setup, 1 point for work, 1 point for the solution)

don't know what that says sorry i can't you

step-by-step explanation:

idk what it says

step-by-step explanation:

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180
