Cos(x) = O/A
Cos(x) = H/A
2
What is the side opposite angle A?
11.6
15.2
7.4
3
Which is the equation for Tan
Tan(X) = O/H
a2 + b2 = c2
Tan(X) = A/H
Tan(X) = O/A
4
When do you use the pythagorean theorem instead of the trig ratios?
When are trying to only find one missing side of right angle
When trying to find a missing angle in right triangle
When trying to find an angle and side
When you don't know what to do
5
In what Trigonometry ratio can we use to calculate the angle?
Cosine
Tangent
Sine
6
When do you use the inverse trigonometry functions?
When you have an angle and a side
When you are trying to find the missing angle
When you have two sides
When you have all the angles
7
What are the first two buttons do you push on the calculator to type in an inverse function?
2nd and a trig button
2nd and mode
2nd and multiply
2nd and the fraction
8
What is the name of the side that is missing?
Hyp
Adj
Opp
9
What is the formula used to solve for C
15 / sin 23 = c / sin 77
c / sin 80 = 15 / sin 77
c / sin 23 = 15 / sin 77
sin 77 / c = sin 23 / 15
