The perimeter of an isosceles right triangle is 12 + 12 sq rt 2. What is the length of the hypotenuse of the triangle? Choose the correct answer: A) 5 B) 6 C) 7 D) 8.485 E) 8
side of triangle is a then perimeter = a+ a +a.sqrt2 ( right angle and pythagorus) =2a +a .sqrt 2 = 12 + 12 Sqrt2 or,   a. ( 2+ sqrt2) = 12(1 + sqrt2), a= 12*(1+sqrt2)/2+sqrt2 =12*2.414/3.414 = then hypotenuse = 8.485   8.485
