If the hypotenuse of a right triangle is a=3cm, so A=90 degrees, and the square of the sum of the other two sides is 17, what is the area of the triangle? so basically, (b+c)^2=17 I think you are supposed to use trigonometry to solve it but I don't know h...

Well, if your equations are correct (which they are), then simple multiply 525 N, which is mg or weight, by the cosine of 30, then by the sine of 30.
