8, because the two minuses add up and turn into positive and 1/5 adds to 4/5 and turns into a whole 1 and adds 7 equal 8
M=-2+-4
———=2/1=1
4 + -3
(4,3 ), (-2,-4)
(X1,y1)(x2,y2)
The formula is L = 2 pi r * (angle measure / 360). We have everything we need to solve this, the angle is 90 and the radius is 12: L = 2 pi (12) (90/360). Do the work inside the parenthesis first to get : L = 2 pi (12)(.25). Solving for L: L = 6pi
Answer:
more ... The same shape and size, but we are allowed to flip, slide or turn. In this example the shapes are congruent (you only need to flip one over and move it a little). Angles are congruent when they are the same size (in degrees or radians). Sides are congruent when they are the same length.
