If r, p, and q are given, then explain whether the Law of Sines or the Law of Cosines should be used to solve for ∠Q. Law of Cosines, two sides and the included angle are known
Law of Cosines, all sides are known
Law of Sines, two sides and an opposite angle are known
Law of Sines, two angles and the included side are known

Law of Cosines, all sides are known

Step-by-step explanation:

q² = p² + r² − 2pr cos(Q) or

= cos (Q)

Q =

except a rational number. : )

g(x) = x² + 2

step-by-step explanation:

it is given that the graphs are the same shape.

the only difference is that the red graph is 2 units higher than the blue graph.

that is to say that the red graph is simply the blue graph that has been moved vertically by 2 units in the positive y direction.

hence

g(x) = f(x) + 2

or

g(x) = x² + 2
