You can put this solution on YOUR website! legs are x and x+5
area = x(x+5)/2=250
x(x+5)=500
x^2+5x-500=0
=
x=20 or x= -25 but x must be > 0 so solution is x=20
Answer: lengths of legs are 20 and 25 inches
You can put this solution on YOUR website! The formula for the area of a triangle (abc)is:
, where b is the base of a triangle and h is the height
The base and height of a triangle must be perpendicular to each other, then in a right triangle height is equal to the leg of the triangle, in this case a=h
you have given A= 250, h=5
Substitute and simplify:
then:
b = 100
Answer: the lenght of second leg of the right triangle is 100 in
