**Find The Measure Of Exterior Angle**. Thus, 70° + 60° + 65° + 40° + x =. The formula for the exterior angle.

Find the measure of the exterior angle new questions in math. Ex 3.2, 2 find the measure of each exterior angle of a regular polygon of (i) 9 sideswe know that exterior angle = (360°)/𝑛 where n is the number of sides of regular polygon. Thus, 70° + 60° + 65° + 40° + x =.

### A + 54 = 2A Subtract A From Both Sides.

Remember, the sum of the exterior angles of any polygon. The sum of two interior angles in a triangle is equal to an exterior angle's measure. Ex 3.2, 2 find the measure of each exterior angle of a regular polygon of (i) 9 sideswe know that exterior angle = (360°)/𝑛 where n is the number of sides of regular polygon.

### The Exterior Angle Theorem States That The Measure Of An Exterior Angle Is Equal To The Sum Of The Measures Of The Two Remote Interior Angles Of The Triangle.

If you already have the other exterior angle measurements, you can use those to help you find your missing measurements! In the given figure, find the value of x. An exterior angle of a triangle is equal to the sum of the opposite interior angles.

### Formula To Find The Measure Of An Exterior Angle Of An Equilateral Triangle Is \(\Frac{{{{360}^ \Circ }}}{N}\) Where \(N\) Is The Number Of Sides.

The exterior angle theorem states that the measure of an exterior angle is equal to the sum of the measures of the two remote interior angles of the triangle. The exterior angle is the angle between any side of a shape, and a line extended from the next side. Supplementary angles are two angles that add up to 180 degrees.

### Thus, 70° + 60° + 65° + 40° + X =.

Every triangle has six exterior angles (two at each vertex are equal in measure). Then set up an equation with the help of the exterior angle sum theorem. The measure of each exterior angle in a regular polygon is 360°/n, where n is the number of sides.

### This Corresponds To The Sum.

A polygon is a plane shape bounded by a finite chain of straight lines. Subtract the known interior angle from the exterior angle: When we add up the interior angle and exterior angle we get a straight.
