The common difference of the data set of A is 1. While the common difference in the data set of B is 0.80
B.) 3.8 + 0.80 = 4.60
4.6 + 0.80 = 5.40
5.4 + 0.80 = 6.20
6.2 + 0.80 = 7.00
Complementary angle is 33.1
Supplementary angle is 123.1
This is because complementary angles, when added together are 90 degrees.
Supplementary angles equal 180 degrees.
8160 dived by 85 equals 96, 2880 divided by 30 equals 96, therefore she can make 96 necklaces
