Answer:


√(8)----- 2units,2units


√(7) ------√(5)units,√(2)units


√(5)-------1unit,2units


3------2units, √(5)units

Explanation:

Use pythagorean's theorem to solve each pair individually.

The instructions say that you have the two sides (a and b) and you have to match it with their hypothenuse.


Formula: c^2=a^2+b^2

1.
a=√(5), b=√(2)

Plug this into the formula.


c=\sqrt{(√(5) )^2+(√(2))^2 }

The square here eliminates the roots.


c=√(5+2)\\ c=√(7)

2.
a=√(3), b=4


c=\sqrt{(√(3) )^2+(4)^2}\\ c=√(3+16)\\ c=√(19)

3.
a=2, b=√(5)


c=\sqrt{(2)^2+(√(5))^2 }\\ c=√(4+5)\\ c=√(9)\\ c=3

4.
a=2, b=2


c=√((2)^2+(2)^2)\\ c=√(4+4)\\ c=√(8)

5.
a=1, b=2


c=√((1)^2+(2)^2)\\ c=√(1+4)\\ c=√(5)
