Answer:
The hypotenuse length = 2
To answer your question if a side is given as a square root of a number, squaring that side will be the number under the square root
Thus (√3)² = 3
Explanation:
The Pythagorean theorem states that :
c² = a² + b²
Once we find c² by adding a² and b² we take the square root of the sum
where
c= hypotenuse and a, b the other two sides
In the figure
a = √3, b = 1
a² = (√3)² = 3 (because (√a)² = a)
b² = 1² = 1
a² + b² = 3 + 1 = 4
Therefore
c² = 4
c = √4 = 2
