**How To Find Exterior Angles Of A Triangle Calculator**. Enter the values that you have. The exterior angle d is greater than angle a, or angle b.

This corresponds to the sum of both angles. 2) the interior angles of a triangle always add up to 180° while the exterior angles of a triangle are equal to the sum of the 2 interior angles that are not adjacent to it. Find the size of angle a°.

### Using The Formula, We Find The Exterior Angle To Be 360/6 = 60 Degrees.

For this example we will look at a hexagon that has six sides. In order to calculate the interior angles of a polygon, you need to first determine how many sides the polygon has. Don't fill in the textfields of the values you want to solve.

### For Example, An Area Of A Right Triangle Is Equal To 28 In² And B = 9 In.

On this page, you can solve math problems involving right triangles. The formula for calculating the size of an exterior angle in a regular polygon is: Of course, our calculator solves triangles from any combinations of.

### Enter The Values That You Have.

Exterior angle of regular polygon is calculated by dividing the sum of the exterior angles by the number of sides and is represented as ∠exterior (regular polygon) = (2*pi)/nsides (regular polygon) or exterior angle of regular polygon = (2*pi)/number of sides of regular polygon. How to calculate the angles of a triangle. How to calculate an exterior angle?

### Step 2 Soh Cah Toa Tells Us We Must Use C Osine.

Since the angles in an equilateral triangle are equal, we have to divide 180° by 3 to get the measure of an angle. Step 1 the two sides we know are a djacent (6,750) and h ypotenuse (8,100). They are equal to the ones we calculated manually:

### Now, We Subtract This Angle From 360° To Find The Measures Of The Other Two Exterior Angles:
