Use Inverse Trigonometric Ratios You can use a calculator and the sine, cosine, or tangent to find the measure of the angle, called the inverse of the trigonometric ratio. Use a calculator to find the measure of ?T to the nearest tenth.The measures given are those of the leg opposite
T and the hypotenuse, so write an equation using the sine ratio. sin T = opp hyp sin T = 2934
