Question

a right triangle has legs of lengths 6 and 3, what is the length of the hypotenuse to the nearest tenth

Answer 1

x = 6.7

Explanation:

legs of a right triangle are 6,3 and hypotenuse be x

using pythagors theorem to find hypotenuse

a^2 + b^2 = c^2

6^2 + 3^3 = x^2

36 + 9 = x^2

45 = x^2

`√(45) = x`

`√(3*3*5) = x`

`3√(5) = x`

6.70 =x

6.7 =x
