Question

pythagorean distance
what is the distance c?
pythagorean formula \\( c^2 = a^2 + b^2 \\)
(chart and grid with points, a=7, b=7, c=? )

Explanation:

Step1: Identify a, b values

From the graph, \(a = 7\), \(b = 7\).

Step2: Apply Pythagorean formula

Use \(c^2=a^2 + b^2\). Substitute \(a = 7\), \(b = 7\):
\(c^2=7^2 + 7^2=49 + 49 = 98\).

Step3: Solve for c

Take square root: \(c=\sqrt{98}\approx9.9\) (matches \(\sqrt{98}\approx9.9\) from options).

Answer:

\(\sqrt{98}\approx9.9\) (or the option with \(\sqrt{98}\) / 9.9, depending on the choice context)
