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....!!!
