Answer:
tan ∅ = 16/12
Step-by-step explanation:
Once again here are the trigonometric ratios
Sin = Opposite over Hypotenuse
Cos = Adjacent over Hypotenuse
Tan = Opposite over Tangent
We are asked to find tan ∅
Looking at the trigonometric ratios we see that tan = opposite over adjacent
So we find the side length opposite of the indicated angle (∅) which would be 16 then we find the angle adjacent angle ( the side that is not the hypotenuse nor the opposite ) so the adjacent of angle ∅ is 12
so tan ∅ = opposite (16) over adjacent (12)
tan ∅ = 16/12

The square of a binomial expands as follows:

Expanding all the binomials, we have

Sum like terms:

Simplify terms appearing on both sides:

Move all terms involving k to the left and all numbers to the right:

Divide both sides by -20:
