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.

Which of the following could be the sides of a right triangle? Check all that apply.
VLD [36.1K]
A. & D. are the correct answers

To answer this, you square the first 2 numbers in the sequence, and then add them together. You then square the 3rd number and put it equal to the first numbers that you added together. If the two sides equal each other, it is correct!

Ex.:

10, 24, 26

10^2 + 24^2 = 26^2
100 + 576 = 676
676 = 676

18, 24, 30

18^2 + 24^2 = 30^2
324 + 576 = 900
900 = 900
