Then by trigonometry , we have
[Sine of an angle is the ration of the side opposite to the angle and the hypotenuse of a right triangle.]
Also ,
Let x be the measure of the third angle.
BY Angle sum property of triangle , we have
Therefore , the measures of all angles in the triangle : 90° , 60° and 30° .
