*In Exercises 15 to 20, use the sine, cosine, or tangent ratio to find the lengths of the indicated sides to the nearest tenth of a unit.*

To determine

**To find:**

The lengths of the indicated sides to the nearest tenth of a unit using the sine, cosine or tangent ratio.

Explanation

**Given:**

The triangle with the indicated sides is shown below.

**Definition used:**

The trigonometric ratios:

**Calculation:**

Let

From the figure we see that

We need to find the values of *x, z*.

We have

We have

Let us use Ti-83 calculator to find the value of

Press

Since we need to find the value of degree, we need to change the mode to degrees.

Press

Let us find the values, correct to four decimal places.

Since we need the values of
