The table below gives 45 students, classified according to their scores obtained in an examination. They are lined up according to their scores.
In the figure, triangle ABC is equilateral.
In the figure O is the centre of the circle and A, B, C are points on the circle. AOB = 50^, BOC = 80^.
In the figure, a sector of the circle with central angle 120° is given. If a dot is put in the circle without looking, what is the probability that the dot is in the shaded region ?
What is the diameter of the circle in the figure ?
Consider the above figure and read the following statements. Statement 1: The length of the tangent drawn from the point P to the circle is 24 centimetres. If OP is 25 centimetres, then the radius of the circle is 7 centimetres. Statement 2: A tangent to a circle is perpendicular to the radius through the point of contact. Now choose the correct answer from those given below.
Calculate the area of triangle ABC.
In the figure one side of the triangle is 10 centimetres and angles on that side are 60° and 45°. Calculate the area of the triangle.
