If two lines in a triangle are each 16 feet and form a right angle, how long will the third line be?
I guess you mean each leg is 16 ft. Then we are searching for the hypotenuse.
We can use this formula:
a^2 + b^2 = c^2
Let a = 16 ft and let b = 16 ft
We are searching for c.
(16)^2 + (16)^2 = c^2
256 + 256 = c^2
512 = c^2
We now take the square root of both sides of the equation.
c is approximately 22.63 ft.
I rounded to two decimal places.
I hope this helps.
