The figure below shows a right triangle:
what is r/q equal to (6points)
a. sin x°
b. cos y°
c. cos x°
d. tan y°

The correct answer is option C.  Cos x

Step-by-step explanation:

Points to remember

Trigonometric ratios

Sin θ  = Opposite side/Hypotenuse

Cos θ = Adjacent side/Hypotenuse

Tan θ = Opposite side/Adjacent side

From the figure we can see that, a right triangle with angles  and sides are given.

To check the options

1) Sin x = Opposite side/Hypotenuse  = p/q

2). Cos y = Adjacent side/Hypotenuse  =p/q

3). cos x= Adjacent side/Hypotenuse  = r/q

4). tan y = Opposite side/Adjacent side = r/p

Therefore the correct answer is option C.  Cos x

cos x

Step-by-step explanation:

r/q represents the sine of angle y:  opposite side  /  hypotenuse.  

In terms of x, r / q is the ratio adjacent side / hypotenuse, which is cos x.

the terms of a geometric sequence can be found by beginning with the first term and multiplying by the common ratio repeatedly. a recursive formula for a geometric sequence with common ratio r is given by an=ran−1 a n = r a n − 1 for n≥2 n ≥ 2 .
