In the parallelogram PQRS, PE is perpendicular to QR. Find the area of the parallelogram.

In the figure PT is a tangent to the circle with centre at O. If PQT = 30o, find the value of PTO

From the figure, calculate TH in centimeters

In diagram, PQ || ST and < PQR = 120º, < RST = 130º, find the angle marked x

In the diagram, O is the centre of the circle. OM||XZ and < ZOM = 25º. Calculate ∠XYZ
