Where you take a word problem and turn it into an equation
I think it's 720
Have a GREAT day!
We start with the more complicated side which is the left side, and show that, on using some trigonometric identities, we will get the term on the right side .

Using Quotient identity for tangent function, we will get


Taking out sine function from the numerator

Cancelling the common term of numerator and denominator

3 to the power of 1 simplified, is just 3.
