TRIG Review! :) 

 

Theta= = generic symbol for an angle

To find angle Ɵfrom two sides you use inverse function (meaning Tan ^-1 or  Sin ^-1  or cos  ^-1 ) then the side divided by the side

                        Example: Tan Ɵ=(11\14) so......
                                                               in your calculator: 2nd tan (11/14)=38.157..... so Ɵ=38.2

Other Reminders: 

• Use Significant Digits for Sides  (Use the lowest amount of sig digs)
• Use one decimal spot for angles (##.#)
