Finding an angle with sine law
WebHow to Use the Sine Function to Find the Angle of a Right Triangle Finding the angle of a right triangle is easy when we know the opposite and the hypotenuse. Question What is … WebStep 1/2. 1) It is necessary to know at least one angle in a triangle to use the law of sines because the law of sines involves ratios of the sides of a triangle to the sines of their opposite angles. If you do not know any of the angles, you cannot use the law of sines to solve for any of the unknown sides. View the full answer.
