*In Exercises 5 to 8, state the ratio needed, and use it to find the measure of the indicated angle to the nearest degree.*

To determine

**To find:**

The measure of the angle indicated to the nearest degree.

Explanation

**Procedure used:**

In any right triangle ABC with

**Calculation:**

**Given:**

The above given figure is a rhombus.

By the properties of a rhombus, all of its sides are equal in length, the diagonals intersect each other at right angle and each of the diagonal bisect the angle at the vertices, we have

Here, ‘O’ is the point of intersection of the diagonals AC and BD
