One angle is a right angle. The measure of a second angle is x/li The length of the hypotenuse is

Question

In the triangle shown, what is the value of $\cos x °$ ?

Accepted Answer

The correct answer is 11 28 . The cosine of an acute angle in a right triangle is defined as the ratio of the length of the leg adjacent to the angle to the length of the hypotenuse. In the triangle shown, the length of the leg adjacent to the angle with measure x &#176; is 11 units and the length of the hypotenuse is 28 units. Therefore, the value of cos x &#176; is 11 28 . Note that 11/28, .3928, .3929, 0.392, and 0.393 are examples of ways to enter a correct answer.
