(1-cos^2(x)) csc^2(x)=1
one of the trigonometry rules is sin^2(x) + cos^2(x) = 1 if you rearrange this you realize that sin^2= 1-cos^2(x)
we also know that csc^2(x)= 1/sin^2(x) so now you can rewrite your equation as:
sin^2(x) x 1/sin^2(x) = 1
sin^2(x)/sin^2(x) =1
the LHS (left hand side) can cancel down to 1 because the numerator and denominator are the same
so then 1=1 Therefore LHS=RHS
Hope this helps
Answer:
4√73
Step-by-step explanation:
x^2= 12^2 + 32^2
x^2= 144+ 1024
x^2=1168
x= 4√73
For one apple pie, Mimi needs 2 cups of flour and 3 cups of apples, which is 5 cups in all, in order to produce how many cups she would need to make five pies you simply times the number given, number of cups, by 5. So you times 2 by 5, which is 10 and 3 by 5, which is 15 and together that makes 25 cups, 10 cups of flour and 15 cups of apples. If you had three cups of flour and needed to make 20 pies, all you would do is times three by 20, which is 60.
Hope I explained this correctly, if you need any more help, please ask.
