Triangle PQR with side p across from angle P, side q across from angle Q, and side r across from angle R

If ∠P is given and the values of r and q are given, then explain whether the Law of Sines or the Law of Cosines should be used to solve for p.

A) Law of Cosines, all sides are known
B) Law of Cosines, two sides and the included angle are known
C) Law of Sines, all sides are known
D) Law of Sines, two angles and the included side are known

i am sorry i dont have the answer but i know for a fact it is not D) Law of Sines, two angles and the included side are known because i got it wrong

Step-by-step explanation:

your welcome

what do u need to know

step-by-step explanation:

p ÷ r = tan(x)

step-by-step explanation:

given that there is a figure below shows a right triangle: a right triangle is shown with hypotenuse equal to q units and the length of the legs equal to p units and r units.

graph is missing so i will create the graph as per given information.

the angle between the legs having lengths p units and q units is y degrees. the angle between the legs having lengths r units and q units is x degrees.

now we need to find about what is p ÷ r equal to.

so we can use trigonometric ratio tan(x)=[altitude]/[base] to find the value of p ÷ r, because p is the altitude and r is the base.

p ÷ r=tan(x)

hence final answer is p ÷ r=tan(x).
