*will give brianliest*(08.01) the graph shows two lines, a and b.
how many solutions are there for the pair of equations for lines a and b? explain your answer.

Exactly one solution.

Step-by-step explanation:

We have been given a graph of a system of linear equations. We are asked to find number of solutions for our given system.

We know that solution of a system is the point, where both lines intersect each other.

Upon looking at our given system, we can see that our given lines intersect exactly at one point that is .

Therefore, our given system has exactly one solution.

(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

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius
