In a regular pentagon ABCDE, all five sides are equal and all five interior angles are equal. Find the size of one interior angle.
In the figure, PQRS is a rectangle. Two rays QT and QU are drawn from corner Q into the rectangle, dividing the corner angle ∠PQR into three smaller angles. ∠PQT = 22° and ∠UQR = 35°. Find ∠TQU.
In the figure, lines PQ and RS are parallel. A transversal cuts PQ at A and RS at B. The angle ∠QAB = 5x°. The angle ∠SBA = (3x + 60)°. ∠QAB and ∠SBA are co-interior angles. Find ∠QAB.
In the figure, two parallel lines are cut by a transversal. The angle marked p is 32° more than the angle marked q. The two angles are co-interior (sum to 180°). Find p.
