1
tanθ =
opposite/adjacent
opposite/hypotenuse
adjacent/opposite
hypotenuse/opposite
2
What is the Law of Cosines?
a2 = b2 + c2 - 2(b)(c)cosA
sinA/a = sinB/b = sinC/c
cosA/a = cosB/b = cosC/c
a2 = b2 - c2 + 2(b)(c)cosA
3
cosθ =
adjacent/opposite
hypotenuse/adjacent
opposite/hypotenuse
adjacent/hypotenuse
4
When you know ∠A and sides b and c in a triangle, how can you find the area of the triangle?
Not possible with the given information
Area = (A)(b)sinc
Area = (b)(c)sinA
Area = (1/2)(b)(c)sinA
5
What is the Law of Sines?
sinA/a = sinB/b = sinC/c
cosA/a = cosB/b = cosC/c
sinA/b = sinB/c = sinC/a
sinA/a = sinB/b = cosC/c

sinθ =
adjacent/hypotenuse
opposite/hypotenuse
opposite/adjacent
hypotenuse/opposite
