question\nfind the length of the third side. if necessary, round to the nearest tenth.\nanswer attempt 1 out…

Explanation:

Step1: Identify the theorem

Use the Pythagorean theorem (a^{2}+b^{2}=c^{2}), where (c) is the hypotenuse of a right - triangle and (a) and (b) are the legs. Here, (a = 7) and (b=14), and we want to find the hypotenuse (c).

Step2: Substitute values into the formula

(c=\sqrt{7^{2}+14^{2}}=\sqrt{49 + 196}=\sqrt{245}).

Step3: Calculate and round

(\sqrt{245}\approx15.7).

Answer:

15.7
