Susan is flying a kite, which gets caught in the top of a tree. Which equation will allow you to find the length of the tree

• cos (44) = x/90

• sin (44) = x/90

• Tan (44) = x/90

• cos (44) = 90/x

• sin (44) = 90/x

A yacht is anchored 90 feet offshore from the base of a lighthouse. The angle of elevation from the boat to the top of the lighthouse is 26 degrees. The distance between the yacht and the top of the lighthouse is about 100 feet. Which equation will allow you to find the height of the light house.

• Tan (26) = x/90

• Tan (26) = 90/x

• Sin (26) = x/90

• Sin (26) = 90/x

In right triangle ABC, ∠A and ∠B are complementary angles.  The value of cos A = 5/13.  What is the value of sin B?

• 5/13
• 12/13
• 13/12
• 13/5

Select all the true statements

• sin(Θ) = 3/5

• Tan(Θ) = 4/3

• cos (Θ) = 4/5

• cos (Θ) = sin (Θ)

Select all the true statements

• cos (Θ) = sin (90-Θ)

• cos(90-Θ) = 5/13

• Sin(Θ) = 5/14

• Tan(Θ) = Tan(90-x)

Find the value of Θ that makes this statement true

sin(25)= cos(Θ)
