Answer:
Square root of 98
Explanation:
The Pythagorean Theorem states that a^2+b^2=c^2.
This means that the sides are represented by a^2+b^2. In order to find the hypotenuse in this problem, we substitute a and b for 7 and 7.
7^2+7^2=c^2
we do what it shows us and get:
49+49=c^2
from there, we add the left side altogether then square each side to get rid of the root.
98=c^2
√98=√c^2
and since 98 can't have two numbers that multiply together and be the same number, we leave it as is like this:
√98 = c
