Ill give brainliest Write and solve an equation to determine the unknown variable. Then find the measure of the unknown angles.

Your options are:

A. x + 7 + 2x - 40 = 180 One angle is 78 degrees and the other is 102 degrees

B. x + 47 = 180 The unknown angles are both 133 degrees

C. x + 7 + 2x - 40 = 90 One angle is 48 degrees and the other is 42 degrees

D. x + 7 = 2x - 40 The unknown angles are both 54 degrees ​

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.
