1. a = 68 b = 112 c = 68

2. a = 127

3 d = 70 b = 40 a = 35 c = 35

OK, Bree....let me see if I can do some of them....[they're a little hard to see!! ]

 

1. a = [180 - 112]  = 68,   b = 112,  c = a = 68

 

2. a = [180 - 15 - 38]  = 127

 

3.   b = 40,  d = 70,   and   a = c  ......we can find these, thusly:

 

b + d + a + c  = 180    and since a = c, we have

 

b + d + a + a = 180

 

40 + 70 + 2a  = 180

 

110 + 2a = 180     subtract 110 from both sides

 

2a = 70   divide both sides by 2

 

a = 35   = c

 

 

4.   a is the complement of 70  = 20

      b is the complement of 20  = 70

      c is the complement of 70  = 20  = a

 

5.  a = b = 90

     c = [180 - 138]  =  42

     d = [180- 132]  = 48

     e = 132

 

6.  a = [180 - 110]  =  70

     c = 25

     b = [180 - 100 - 25 ]  = 55

 

7.  a = b = c  = 54    [pretty easy, huh??]

 

8.  a = [180 - 2*54]  = [180 - 108]  = 72

     b = [180 - 54]  =  126

 

I did them hurriedly.....check to see that I didn't make any mistakes....!!!

 

 

cool cool cool
