Question

a right triangles hypotenuse is 6m and one legs is 2 square root 5 m. find the length of the other leg

Answer 1

use pythagoras
6^2 = (2sqrt5)^2 + x^2
x = sqrt(36 - 20)

Answer 2

\(\Large \color{MidnightBlue}{\Rightarrow (2\sqrt{5})^2 + x^2 = 6^2 }\)

Answer 3

This is the Pythagorean theorem

Answer 4

\[b=\sqrt{c^2-a^2}\]
where c is the hypotenuse and a is the leg
as parth mention pythagorean theorem
\[c^2=a^2+b^2\]
where c=hypotenuse
a, b are the legs
