Question 67680: How do you find the area of a right triangle when the height is not known, and the only angle known is 90 degrees. I know that length of the base is 5.56 and the length of the longest side is 1134.4 Answer by rajagopalan(174) (Show Source):
You can put this solution on YOUR website! ****
one side =1134.4, Square of side 1286863.36,(A)
Other 5.56, Square of side 30.9136 (B)
difference of squares = (A-B)1286832.446
So third side =square root of 1286832.446 = 1134.386374
Area = 1/2*b*h = 0.5*5.56*1134.386374= 3153.59412 sq units
OK.
