Answer:
don't know that sorry can you help me though
The answer to the following equation is the first one.
If you want the intersect of M and N, then:
M∩N = {4,7} (common part in M AND N)
% Increase = Increase/original number x 100
Let I represent increase
((58-32)/32) x 100 = I
58oz - 32oz = 26oz
26/32 x 100 = I
0.8125 x 100 = I
Increase = 81.25%
C: tan 50 degrees that's your answer
