thanks so much

Because the angle is 35 and that is 12cm of the 90 degress we can subtract the poliosis. That will give us 2 and you square it for 4  :)

let's analyze what we have. as always the side opposite the right angle it the hypotenuse, so we're working with either sine or cosine. the 500 is opposite the 10 degree angle
sin(10)=500/x
