Do you talk romanian. and i think that it is g.
<span>According to trigonometric the formula for sin is
sin = opposite/hypotenuse.Sin is defined as the ratio of sides of a right angled triangle.Hypotenuse is the is the longest side of a right-angled triangle,which is the side opposite of the right angle.So the the hypotenuse is clearly 1.3, so you divide 0.5/1.3
Hence the answer is around 0.38
The result is Angle2..</span>
<span>(x+3)^2 = x^2 + 69
x^2 + 6x + 9 = x^2 + 69
x^2 + 6x + 9 - x^2 = x^2 + 69 - x^2
6x + 9 = 69</span>
