belka [17]

Answer:

Brain travelled 687.68 from the cliff.

Step-by-step explanation:

Given that:

Height of the cliff = 520

Base of the cliff = 450

The distance will form the hypotenuse of right angled triangle.

Pythagorean theorem states square of hypotenuse of right angled triangle is equal to the sum of squares of base and height of triangle.

Using pythagorean theorem;

a = 520, b=450, c = hypotenuse

a^2+b^2=c^2\\(520)^2+(450)^2=c^2\\270400+202500=c^2\\472900=c^2\\c^2=472900

Taking square root on both sides

\sqrt{c^2}=\sqrt{472900}\\c=687.68

Hence,

Brain travelled 687.68 from the cliff.
