Answer:
It is an identity, the proof is in the explanation
Step-by-step explanation:
csc(A)-cot(A)=tan(A/2)
I'm going to start with right hand side
tan(A/2)=(1-cos(a))/(sin(a)) half angle identity
tan(A/2)=1/sin(a)-cos(a)/sin(a) separate fraction
tan(A/2)=csc(a)-cot(a) reciprocal and quotient identities
Answer:

The probability of getting 1,2,or 4 is .75 or 75%
I’m not sure what the question is, so if you could tell me what the actual question is I might be able to answer it!
Your bases are like: they are both x. When you multiply like bases with exponents, you add the exponents together to get the new power. But you can't add those til you get a common denominator. That's 20. So your problem looks like this:

which gives you

. That's your answer!
