Soh Cah Toa
Hypotenuse = 13.6 Adjacent =13 Opposite = 4
Find angle using Cos-1
17.08 degrees
Find the missing side: Theta = 38 Adjacent = 13 Opposite = x
What is 10.16?
What trig function will tell us the angle if we know the opposite and hypotenuse?
What is the Sin-1
Hypotenuse = 13 Opposite = 12 Adjacent = 5
Find the angle using an inverse trig function
67.38 degrees
Find the missing side: Adjacent = x Theta = 61 Hypotenuse = 11
What is 5.33?
In triangle ABC, angle A is a right angle. If cos b is 7/11, find tan b.
tan b = 8.49/7.
What is opposite over adjacent?
What is Tan?
Opposite = 6.7 Hypotenuse = 9 Adjacent = 6
Find the angle using Tan-1
41.85 degrees
Find the missing side: Theta = 58.7 Adjacent = 5 Opposite = x
What is 8.22?
In triangle ABC, angle A is a right angle. If cos c = 9/14, find sin b.
sin b = 10.72/14
What ratio will give us the angle when used with the Cos-1?
Adjacent over Hypotenuse?
Hypotenuse = 7.07 Opposite = 5 Adjacent = 5
Find both angles using any method
45 and 45 degrees
Find the missing side: Opposite = 4 Adjacent = x Theta = 44.8
What is 4.03?
In triangle ABC, angle A is a right angle. If cos a = 12/15, find the tan a.
tan a = 9/12
