Question

Find the exact length of the third side.

Answer 1

The third side is equal to 50

Explanation:

`a^(2) + b^(2) = c^(2)`

30^2 + 40^2 = c^2

900 + 1600 = c^2

2500 = c^2

find square root of 2500

50 = c

Answer 2

50

Explanation:

Using the pythagorean theorem:

a²+b²=c²

30²+40²=c²

900+1600=c²

c²=2500

c=50
