The cosine ratios which are correct for the ΔPQR are CosineP = r/q and CosineR = p/q.
We have,
Δ PQR,
Length of hypotenuse PR = q
The length of PQ = r,
And the length of QR = p
NOw,
We know that Trigonometric ratios of CosineΘ;
CosineΘ = Base/Hypotenuse
So,
CosineP = r/q
And,
CosineR = p/q
So, from the above find out values we can say that these values are given in option (a) and option (d).
Therefore, the cosine ratios which are correct for the ΔPQR are CosP = r/q and CosR = p/q.

Answer:
y = 1/3x -1
Step-by-step explanation:
We have 2 points (9,2) and (42,13)
We can find the slope
m = (y2-y1)/(x2-x1)
= (13-2)/(42-9)
=11/33
=1/3
The slope is 1/3
We can use the point slope form of the equation
y-y1 = m(x-x1)
y-2 = 1/3(x-9)
Distribute
y-2 = 1/3x -3
Add 2 to each side
y-2+2 = 1/3 x-3+2
y = 1/3x -1
