Find the sine of the angle A of a right-angled triangle ABC in which the hypotenuse of AC is 5 and the leg CB is 3.

In order to find the sine of an angle in a right-angled triangle, it is necessary to divide the length of the opposite leg by the length of the hypotenuse of the triangle.

Calculate the sine of the angle if the leg is 3 and the hypotenuse is 5.

sin = 3 ÷ 5 = 0.6.

Answer: The sine of the angle is 0.6.
