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:
I only have number 2 but it's C
Step-by-step explanation:
You have to multiply 18.25 3 times since volume of cube is length * width * height
If you do a check (plug in your answer to y) that would be your reason
Answer: A 9 min
Step-by-step explanation: 54/6=9
<h2>
(9) </h2>
<em><u>-6-6-6-6-6-6-6-6-6</u></em>=-54
If they are similar they are by a ration of 1:2 but you dont know all the angles or all the sides.
