Exercise 58 Page 678

So far we've learned some methods to solve triangles like the Law of Sines, the Law of Cosines, and the trigonometric ratios. Depending on the type of triangle and the parts we are given, we can apply them to solve the triangle.

In the table below, we will write which method to use to solve a triangle depending on the type of triangle and the given parts of it.

To Solve	Given	Use
A right triangle	Leg-Leg	Tangent ratio
	Hypotenuse-Leg	Sine or cosine ratio
	Acute Angle-Hypotenuse	Sine or cosine ratio
	Acute Angle-Leg	Sine, cosine, or tangent ratios
Any triangle	Angle-Angle-Side	Law of Sines
	Angle-Side-Angle	Law of Sines
	Side-Angle-Side	Law of Cosines
	Side-Side-Side	Law of Cosines
