B. adding 40 to both sides of the equation
x^2 - 40 = 0
x^2 = 40
x = ± √40
Answer:
first you need to place a point for the vertex of the new angle. then take the compass and place it on the vertex of angle DBC and draw a circle around it. without adjusting the compass, move it to the vertex that you had placed and draw the same size circle around it. Draw a base line for the new angle . Then go to the point of intersection on angle DBC where the circle intersects both of the sides. place your compass on both intersection points. move that to the point of intersection on the new angle and draw a circle. then connect the points.
The distance is 6 I think
To find the circumference of a circle you have to multiple the radius by 2 and also by pi. So, to find the radius when given just the circumference, who have to do the reverse operation and divide the circumference by 2 and also by pi to get the answer of 22.92993631, which you could of course round.
