Answer 1

Explanation:

here x is hypotenuse because it is the side opposite to largest angle.

12 and 15 are the two other legs of the triangle .so let them be a and b rectively . And let hypotenuse be c.

according to the pythagoras theorem

a^2 + b^2 = c^2

12^2 + 15^2 = x^2

144 + 225 = x^2

369 = x^2

`√(369) =x`

`3√(41) =x`
