In Exercises 21 to 26, find the measures of the angles named to the nearest degree.

To determine

**To measure:**

The angle named to the nearest degree.

Explanation

In a right angle triangle,

1) The side *PQ*, which is opposite to the right angle *PRQ* is called the **hypotenuse**.

(The hypotenuse is the longest side of the right triangle.)

2) The side *RQ* is called the **adjacent **side of angle

3) The side *PR* is called the **opposite** side of angle

**Formula used:**

**Given:**

By using Pythagoras theorem, that is

Let *b* be the adjacent side of the triangle.

From, the diagram we have

For angle *x* and hypotenuse side is 3*x*
