You have it selected correctly. 20 is the only option.
Answer: Choice C
x/w and z/(y+v)
======================================================
Explanation:
All answer choices have that first fraction with a denominator of w. This implies that AB = w is the hypotenuse. This only applies to triangle ABD.
Focus on triangle ABD. It has an opposite leg of AD = x, when the reference angle is ABD (or angle B for short).
So we can say sin(ABD) = opposite/hypotenuse = AD/AB = x/w
x/w is one of the answers
-----------
Also note how y+v is the same for each denominator in the second fraction. y+v is the hypotenuse of triangle ABC. When the reference angle is ABD (aka angle ABC), the opposite side of this same triangle is AX = z
Therefore,
sin(ABD) = sin(ABC) = opp/hyp = AC/BC = z/(y+v)
z/(y+v) is the other answer
Side note: triangle ACD is not used at all.

Im not sure ut it looks like 3x over 3x would cancel eachother out.
Answer:
ln (27 x²)
Step-by-step explanation:
Given in the question an expression
3 ln 3 + 2 ln x
Step1
Apply power rule
ln 3³ + ln x²
Step2
Apply multiplication rule
ln (3³ . x²)
3³ = 27
so
ln (27x²)
