Question

Find the missing length for a right triangle with hypotenuse of 18 and a leg length of 6. Round to the nearest whole number if necessary. (1 point) a) 17 b) 324 c) 19 d) 36

Answer 1

If you want it rounded its 16.97 or 16.9

Answer 2

$a^2 + b^2 = c^2$

$a^2 + 6^2 = 18^2$

$a^2 + 36 = 324$

$a^2 = 288$

$a = \sqrt{288}$

$a = \sqrt{144 \times 2}$

$a = 12\sqrt{2}$

$a \approx 17$
