Question

Please tell me how to do it

Answer 1

3 sqrt(13)

Explanation:

Since this is a right triangle, we can use the Pythagorean theorem

a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse

6^2 + 9^2 = c^2

36+81 = c^2

117 = c^2

Take the square root of each side

sqrt(117) = sqrt(c^2)

sqrt( 9*13) = c

sqrt(9) sqrt(13) =c

3 sqrt(13) =c
