Measurement of two adjacent angles are `35^@ and 145^@`. Let’s write how the external sides of those two angles are situated?

Measurement of each interior angle of a regular polygon is 135^@ . Let's us write the number of sides of the polygon.

Let's write the ratio of the three angles of equilateral triangle.

Measurement of each exterior angle of a regular polygon is 60^@ . Let's write the number of sides of that polygon.

Measurement of each exterior angle of a regular polygon is 144^@ . Let's write by calculation the number of sides of the polygon.

Let's write the ratio of the angles of a right angled isoceles triangle.

Let's write the ratio of the angles of a right angled isoscale triangle.

The three angles of a triangle are x^@, 2x^@ and 3x^@ . Let us find the measure of the greatest angle.

The measures of the sides of a triangle are 3,5 and 7 then the greatest angle of the triangle is-
