I need some help with this simple problem, it has been awhile since I have done any trig but some explaination would be nice. I already have the answer to the problem, but I would like some explaination, thanks!

sin= opp/adj, cos=adj/hypot, tan= opp/adj

fresh stone
#

(this may sound really stupid but i genuinely havent seen this material in a bit haha), but it will be b= h*sin(58 degrees) no?

adjacent is the side touching the angle

opposite is the side not touching the angle

One last thing

#

Whats the answer you got from this?

#

I think my teacher might have had the wrong answer on the mini-quiz they had us do (the length was smaller than the opp and adj which cant happen)
