How to solve for alternate interior angles
WebJan 26, 2024 · The Alternate Exterior Angles Theorem states that if a pair of parallel lines are cut by a transversal, then the alternate exterior angles are congruent. Here we have a new pair of lines, parallel and crossed by a transversal. We are not bothering to identify our parallel lines and transversal! We are jumping ahead to numbered angles. WebWe know that the sum of all the interior angles in this polygon is equal to 720°. The sum of all the angles of the given polygon is: ∠A + ∠B + ∠C + ∠D + ∠E + ∠F = (x - 60) + (x - 20) + 110 + 120 + 130 + (x - 40) = 3x+ 240 Now we set this sum equal to 720 and solve it for x. 3x+ 240 = 720 3x = 480 x = 480/3 = 160 Now, let us find ∠B.
