Please help me solve

Step-by-step explanation:

Because this is a right triangle and you have all the side values, you can use any of the trig identities to solve for angle N. I'll just use sin (no reason; any of them will work and will give you the correct answer as long as you do it properly!)

sin of an angle is the side opposite the reference angle over the hypotenuse. For us, that looks like this:

and

sinN = .3243243243 and then hit the 2nd button and then sin to get:

 and after that set of parenthesis, enter the decimal to get that

N = 18.9 degrees

sorry not knowing about that
