The answer is 75
First you subtract 180 and 165 to find that smallest angle inside the triangle(15). Then you add 15 and 90,the two angles you know, and do 180 - 105= 75.
The trick is that all angles inside a triangle equal 180 degrees. Hope this helps!

Answer:
AR is 3 using Pythagoras 5^2 - 4^2 = 3^2. sin R is just sin (AC/RC). cos is adjacent over hypoteneus. tan is oppositve over adjacent. and sec is 1/cos, csc is 1/sin, and cot is 1/tan.
