trig tools
Contribució de: Moore
you can use any trig tool to determine 
an unknown side length.
If you know the length of the longest side 
of a right triangle and all the angles: 
you will need to use the inverse tangent.
using the sine ratio MUST be 
your only next step.
 you cannot use tangent for your next step.
Given the diagram here, choose the correct next step.
label your diagram then 
choose tangent to start
use pythagorean theorem 
to calculate the height
the question is impossible 
to complete
label your diagram, 
choose cosine to start
Triangle GHJ is a right triangle.
 J = 80o
You would need to use "sine" to calculate a side.
Triangle GHJ is obtuse.
You have triangle GHJ where G = 77o and H = 23o .What conclusion can you make?
To calculate the diagonal distance to the 
ship, use tangent.
 add the two heights then 
use sine to find the 
diagonal distance
You need to use cosine to calculate 
the diagonal distance.
Given the diagram shown, choose the correct statement.
give up - not 
enough info to do 
anything.
You know two sides of a right triangle and you want to 
know another angle value.Which is the MOST correct 
statement?
tangent is certainly the best option.
use cosine.
use the table immediately.
you will need to use the inverse function.
 7.0/5.2
7.0/8.7
5.2/7.0
5.2/8.7
Given this triangle, which ratio is tan A?
10.5/22.1
9.5/22.1
9.5/10.5
22.1/10.5
Given this triangle, which ratio is 
cos U?
