I didn't convert the degree of (?) to gradient on my paper

I think the correct answer is 13.81. maybe you calculate wrong. Try it again. by the way, you're good at Maths. I like Maths too, so we can be friend and learn more about Math.hihi

Let us do it by numbers

450 cos(30) -150 = 389.711 - 150 = 239.711

450 * sin(30) + 750 = 225 + 750 = 975

according to the computer scientific calculator the inverse tan of ( 239.711 / 975) = 13.812 degrees

how did you obtain your answer ????

thanks,
