How do you answer ACTIVITY 25?? THANKS!!!! :)

Sagot :

1)  A = 116
2)  B = 67
3)  A = 169
4)  B = 42
C = 180 - (180-68)-(180-B) = 30
A = 180 - (180-88) - (180-B) = 50
5) C = 144
B = 180-C = 36
A = 180-B -(180-119) = 83
6) C = B = 180-42 = 138
A = D = 180-138 = 42
7) B = 180-93 = 87
C = 180-D = 54
D =180-54 = 126
A = 180-B =93
8) A = 60
B = 84
C = 180-84 =96
9) A = 180-68 = 112
B = 180-45 = 135
10) B = 180-110 = 70
A = 180-70 = 110
