The area of a right triangle is 50. One of its angles is 45 Deg. Find the lengths of the sides and hypotenuse of the triangle.
For a Right angled Triangle, one angle is 90 deg, another angle is 45 deg (given) and the third angle is 45 deg.(180-(45+90)). Therefore, using Pythogorus thoerum, 2x^2=Hypotenuse^2 and another equation (1/2*x*x=50(area of triangle), we can get both x =10 and Hypotenuse=10*root of 2
