11. Parallel lines have the same slope, so the slope of EF is the same as the slope of CD. The slope of CD is found as
.. slope = (difference of y coordinates)/(difference of x coordinates)
.. = (9 -1)/(-1 -(-7)) = 8/6 = 4/3
The slope of EF is ...
.. B. 4/3

12. The perpendicular line is vertical. Its slope is ...
.. D. undefined

Miles had a piece of paper 1/4 of a large circle cut in three equal parts from the center point of the circle. What angle is the

telo118 [61]

The angle of 1/4 of a circle is given by:
(1/4) * (360) = 90 degrees
We now look for the angle that results from dividing 1/4 of a circle into three equal parts.
We have then:
(1/3) * (90) = 30 degrees.
Answer:
the measure of each part is:
30 degrees
