Because on number two there is a right angle and a part of it is 66 you subtract 66 from 90 and then divide that by 31 and subtract 7. Hope that helped a little

2.) If the degree you are looking for is the angel, the answer would be 24.
31x-7+66=90
31x+59=90
-59 -59
31x=31 (divide that by each other)
and get 1. Plug in 1 to x and you get 24. 66+24 = 90

3.) 65x-12=43x+10 (Set them equal to each other since they will be the same measurement because of vertical angels)
65x-12=43x+10
-43x -43x
22x-12=10
+12 +12
22x=22 (divide and you get 1)
Plug those in and you get 35 degrees for your answer to number 3 :)

Answer:

As a former runner upper Senior Class Secretary I can say that your classmates need the following:

1. To be respected, even when others may not respect them.

2. They need a leader who can listen to what they have to say and DO SOMETHING about it.

3. They need the feeling of commitment when given the oppurtunity to improve.

4. They need rules, guidlines and restrictions.

(I would advocate that we have a strong leader....Is it going to be you?)
