The paragraph thing is simply just seeing what you can multiply each by which is 7. The answer is 3/4
Answer:
7 : 14, or simplified, 1 : 2
Step-by-step explanation:
Answer:
60
Step-by-step explanation:
0.7x=42
42/0.7=60
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!
