Supplementary consecutive interior angles

The sum of all 8 interior angles is given by . Since each interior angle has the same measure, we divide by 8 to find the measure of one interior angle: . Each exterior angle is supplementary to this and therefore must have measure 45º. The diagram given below shows a regular pentagon. If point O is the center, what are the measures of angles ... 180(n − 2) = 180(6 − 2) = 720 ∘. We know that the sum of all the interior angles in this polygon is equal to 720 degrees. The sum of all the angles of the given polygon is: ∠A + ∠B + ∠C + ∠D + ∠E + ∠F = (x − 60) + (x − 20) + 130 + 120 + 110 + (x − 40) = 3x + 240. Now we set this sum equal to 720 and solve it for x. ∠3 and ∠4 are vertical angles. ∠5 and ∠8 are corresponding angles. ∠3 and ∠5 are alternate interior angles. ∠2 and ∠8 are alternate exterior angles. All of the above are false. 22. The following diagram shows parallel lines cut by a transversal. What is the measure of ∠2? 80° 100° 20° 160° 50° 23.
