Solution of Right Angled Triangles
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..

If two adjacent angles are supplementary, their exterior arms lie in a straight line. If two lines intersect, the vertically opposite angles so formed are equal. When a number of lines meet at a point, the sum of the angles so formed is 360 ..
