The question given below contain two statements giving certain data. You have to decide whether the data given in the statements are sufficient for answering the question ?
What is the height of a right-angled triangle ?
A. The area of the triangle is 20 times its base.
B. The perimeter of the triangle is equal to that of a square of the side 10 cm.
From statement (A),
20b = (1/2) × b × h
h = 40 cm.
If the length of a chord of a circle is 16 cm and is at a distance of 15 cm from the centre of the circle, then the radius of the circle (in cm) is
In a triangle PQR, PQ = PR and angle Q is twice that of angle P. Then angle Q is equal to
If two circles touch each other internally. The greater circle has its radius as 6 cm and the distance between the centres of the circles is 2 cm. The radius of the other circle is
