A right triangle is drawn, the opposite site of right angle is 10, sum of the sides next to right angle is 12.
What is the area of the triangle?
What is the area of the triangle?
a+b=12
a^2+b^2 = 100 (Pythagorean theorem)
a^2+b^2 = (a+b)^2 -2ab
144 -2ab = 100 or ab 22; Area of triangle = 1/2ab or 11
