a. to find the median find the average of 10 and 22… you should get a 16
b.length of EF is zero… because E and F are the same point.
c. answer is 9.16. since you have the length of 3 sides or a triangle within the trapezoid, you can use the cosine law.. which is a^2 = b^2 + c^2 – 2bc(cosA) A being the side directly across angle a….
and when you do your calculations, you should make A = 10 so you can find angle a.. and with some triginometric manipulations, you’ll end up with 9.16
