trigonometry layout

In Maths we're learning how to find the sides of Angels of a right angle triangle using trigonometry, And to use trigonometry right we had to use the right layout given to us.

Here is how to find the angels of a right-angle triangle and how to lay it out

Step (1) - Draw the diagram and label it.
Once you've finished your diagram move onto step (2)









Step (2) Lay (write) out what you're given
Write the HYP and OPP or if the 12 is in place of the ADJ then the OPP is the ADJ and you'd right it as HYP =  and ADJ =





Step (3) Write out your commentary on how you're going to solve it.
Once you've written your commentary move onto step (4)





Step (4)
Write it out (Press into your calculator what your Opp-Hyp or ADJ for me its 12 over 17 so I press in 12 divided by 17 to get my answer.
Step (4.5)
Then write out another commentary
(Couldn't get the photo in so I'll write out what I stuck)
Commentary - To change the decimal into a Degree we need to use Sin-1

Step (5)
Once you've written out your commentary you need to press shift on your calculator and press sin because it is a valid part of the process of finding out your answer, to find your answer all you need to do its press Shift then sin and put in what you got from your first try mine was 0.7 so I would press shift then sin to get sin-1 and then put in 0.7 and then enter to get my answer.



In the end it should look a bit like this.
