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.
