Answer:
tan (A-B) = ± 4/3
Step-by-step explanation:
COS (A-B) = 3/5
COS² (A-B) = (3/5)² = 9/25 = 1 - sin² (A-B)
sin² (A-B) = 1 - 9/25 = 16/25
sin (A-B) = ± 4/5
tan (A-B) = sin (A-B) / cos (A-B) = (± 4/5) / (3/5) = ± 4/3
We need convert the mixed numbers to improper fractions.
Divide the number by a fraction, this is the same as multiply this number by the reciprocal of the fraction:
I feel like this too sometimes :(( it’s so tuff. i’m even one of the smarter people too and it just seems like there’s no end, but try to talk with your parents. tell them about this. it might not go well at first, but maybe they’ll understand eventually
A cute triangle , i believe
Answer:
Just do what you would do with numbers that are not fractions (or improper fractions), and then divide by that certain number of fractions you are finding the average of.
