Answer:
Choice B. sin(B)=cos(90-B)
Step-by-step explanation:
That cofunction identity is the one you looking for...choice B.
If you aren't convinced or don't know that identity, then maybe this will help:
90-B is actually the same thing as saying A for this right triangle since A+B=90.
So choice B basically says sin(B)=cos(A)
Well let's find both sin(B) and cos(A)
sin(B)=b/c
cos(A)=b/c
Those are the same ratios!
So they are equal!
Answer:
720
Step-by-step explanation:
If order mattered, we would say select the first number (10 choices), then the second (9 choices) then the third (8 choices). So there would be 10 x 9 x 8 = 720 possible choices.
Answer:
9 servings of meat.
Step-by-step explanation:
The first ratio you are given is 8:36. You are trying to figure out what 2:__ is.
8/36 x 2/X
Multiply 2 x 36 and get 72. Now divide 72 by 8 to get 9.
