If A

If a, b, c are the sides of a right triangle where c is the hypotenuse, prove that the radius r of the circle which touches the sides of the triangle is given by r = a + b – c / 2 . B c are the sides of a right triangle where c [...]

If a, b, c are the lengths of three sides of a triangle, then area of a triangle = root s(s – a) (s – b) (s – c) , where s = perimeter of triangle. B c are the lengths of three sides of a triangle If A then area of a triangle = [...]

If (a, b) is the mid-point of the line segment joining the points A(10, – 6), B(k, 4) and a – 2b= 18, then find the value of k and the distance AB. 4) and a – 2b= 18 6 B(k b) is the mid-point of the line segment joining the points A(10 If A [...]

If A, Z, and N denote the mass number, the atomic number, and the neutron number for a given nucleus, we can say that (1) N = Z + A (2) isobars have the same A but different Z and N and N denote the mass number and the neutron number for a given nucleus [...]

If A, B and C are interior angles of a triangle ABC, then show that sin(2/B+C) = cos 2/A. B and C are interior angles of a triangle ABC If A then show that sin(2/B+C) = cos 2/A. October 5, 2020 Category: Chapter 8 - Introduction to Trigonometry , Maths , NCERT Class 10 ,
