AB is a chord of a circle with centre O and P is any point on the circle. If $$\angle APB = 122^\circ$$, then what is the measure of $$\angle OAB$$?
In triangle PQR, points E and F are on sides PQ and PR respectively such that EF is parallel to QR. If PE = 2 cm and EQ = 3 cm, then area($$\triangle$$ PQR) : area($$\triangle$$ PEF) is equal to:
The average weight of a certain number of students in a class is 55.5 kg. If 4 students with average weight 60 kg join the class, then the average weight of all students in the class increases by 360 g. The number of students in the class, initially, is:
