I would say C. and A. Hope this helps.
Answer:
See below.
Step-by-step explanation:
We know that
tanA + tan B
tan (A + B) = ---------------------
1 - tanAtanB
Substituting for A + B
tan (A + B) = tan pi/4 = 1.
tanA + tan B
So ------------------ = 1
1 - tanAtanB
Therefore tanA + tan B = 1 - tanAtanB.
The answer is
3 x - y + 2 = 0
Hope this helps :)
Im pretty sure it would be 54÷ b- 6 if your looking for only the cost of the braclets nothing else.
