formula for calculating inside angle of a triangle

Introduction - When calculating sides or angles of right angled triangles, it is easiest to use the appropriate trigonometric relation. Finding the value of trigonometric ratios from the tables is learnt easily. Nowadays of course calculators are ab..

To solve a right angled triangle, we need to find out the unknown sides and the angles with the help of t-ratios. To find a side, usually we take such t-ratios that involve the unknown sides. We have taken A because, the side opposite to A is the un..

To solve a right angled triangle, we need to find out the unknown sides and the angles with the help of t-ratios. To find a side, usually we take such t-ratios that involve the unknown sides. In the figure, AB = 100 cm, find (i) x and (ii) ..
