A triangle has angles measuring

To determine

**To find:**

The length of the radius of the circumscribed circle.

Explanation

**Formula used:**

Radius of circumscribed circle:

Let

**Given:**

The triangle has angles measuring

**Calculation:**

The angle measures of a triangle are

Here, the angles are

We sketch the figure of the triangle of the circumscribed circle.

By the above figure we take sides measures

Next we find the triangle side â€˜*a*â€™

We find the perimeter of the triangle,

Substituting the values

Then we find area of the triangle,

Therefore,
