The square below has a side length of 5 cm. What is the length of the missing side? Round your answer to the nearest whole numbe

Misha Larkins [42]

Answer:

D. about 7 cm

Step-by-step explanation:

You can use the pythagorean theorem.

You have a triangle with sides of 5 and 5, so that means the third side is:

$a^2 + b^2 = c^2 --> 5^2 + 5^2 = c^2\\25 + 25 = c^2\\50 = c^2\\c = 5\sqrt{2}$

rounding:

$5\sqrt{2} = 7$
