If a circle is divided in half, and that half is divided in half two more times, which of the following is the angle created? A. 18 degrees B. 90 degrees C. 22 1/2 degrees D. 45 degrees?

45 degrees

Step-by-step explanation:

360/2=180

180/2=90

90/2=45

graph them on a graphing calculator, press 2nd trace. select intersect. hit enter until it says answer. ti 84 works best

step-by-step explanation:

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system
