Answer:
C). 10
Step-by-step explanation:
Using the Pythagorean theorem, a^2+b^2=c^2
We know the two sides (a and b) and are trying to find the hypotenuse (c).
Substitute the known values:
7^2+7^2=c^2
Simplify and solve:
49+49=c^2
98=c^2
sqrt(98)=c
c=9.899
Rounded to the nearest whole number would be 10
