Question 185275: tan(45+30)
Answer by feliz1965(151) (Show Source): You can put this solution on YOUR website!
I will set it and you can simplify.
tan45 = 1
tan30 = sqrt{3}/3
We use the following formula:
tan(A + B) = (tanA + tanB)/(1 - tanA(tanB))
Now, tanA = 1 and tanB = sqrt{3}/3
All you have to do and plug and chug.
Can you finish now?
