Question

c 18 km 80 km what is the length of the hypotenuse? if necessary, round to the nearest tenth. c = kilometers submit

Explanation:

Step1: Identify the formula

For a right triangle, the Pythagorean theorem is \( c = \sqrt{a^2 + b^2} \), where \( a = 80 \) km, \( b = 18 \) km.

Step2: Calculate \( a^2 + b^2 \)

\( a^2 = 80^2 = 6400 \), \( b^2 = 18^2 = 324 \). Then \( a^2 + b^2 = 6400 + 324 = 6724 \).

Step3: Find the square root

\( c = \sqrt{6724} \approx 82.0 \) (rounded to the nearest tenth).

Answer:

82.0
