The perimeter of an isosceles right triangle is 8 + 8 sq rt 2. What is the length of the hypotenuse of the triangle?  Pick one:	A) 4	B) 5.656	C) 5	D) 6	E) 7
side of triangle is a then perimeter = a+ a +a.sqrt2 ( right angle and pythagorus) =2a +a .sqrt 2 = 8 + 8 Sqrt2 or,   a. ( 2+ sqrt2) = 8(1 + sqrt2), a= 8*(1+sqrt2)/2+sqrt2 =8*2.414/3.414 =0.707*8=
