Triangle abc has the angle measures shown. which statement is true about the angles? ma= 20° ma= (2x) mb = (5x)" mc = (11x) mb = 50° ma and m8 are complementary ma+ mc = 120°

Ijust need to see how to do this. so you don’t have to answer all of them just a step by step explanation of one.

At the olympic games, many events have several rounds of competition. one of these events is the men's 100-meter backstroke. the upper dot plot shows the times (in seconds) of the top 8 finishers in the final round of the 2012 olympics. the lower dot plot shows the times of the same 8 swimmers, but in the semifinal round. which pieces of information can be gathered from these dot plots? (remember that lower swim times are faster.) choose all answers that apply: a: the swimmers had faster times on average in the final round. b: the times in the final round vary noticeably more than the times in the semifinal round. c: none of the above.
