Answer: Here, side a = 30ft.
side b = 40ft.
Hence according to, Pythagoras theorem,
h²=p²+b²
where, h= hypotenuse of the triangle
b= base of the triangle
p= perpendicular of the triangle
Explanation:
hypotenuse c {according to question} - c=
therefore, c=
= 50ft. will be the answer.
Hypotenuse means the longest side of the triangle or in other words the side opposite to the 90° angle of the triangle.
