Answer:
10
Step-by-step explanation:
it is because of Pythagoras's theorem: that the sum of the squares of the two lines that form a right angle, must add up to the square of the hypotenuse (c). So 6²+8² is 100, which is the square of 10.
Pythagorean Theorem tells us that (6)a^2 plus (8)b^2 = (10)c^2
6^2 = 36
8^2 = 64
36 + 64 = 100
sqrt of 100 = 10
c = 10
