We know that the large angle is 90 degrees as it is a right angle. Thus, (I don't know how to include degree symbols). We solve: , so then . Thus, x is forty degrees and the answer is B.
There is a bisector splitting a 90-degree angle into 2 parts, we are given that one of them is 10. This can only mean the other side is 80 degrees in total.
The first week Kevin got 12.25 you divid that by 4 then multiply the answer by 3 and you do the same for the next week then you add them together to get your answer which should be $21.93
