Answer:
Answer is 6.40 units
Step-by-step explanation:
Pythagorean theorem
a^2+b^2=c^2
fill in the sides for a and b
4^2 + 5^2 = c^2
simplify
16+25 = c^2
41 = c^2
Sqrt both sides
c = 6.4
6.40 units
You can use the equation a^2+b^2=c^2 for this. C is the unknown and the hypotenuse.
In this case, 4^2+5^2=c^2.
16+25=c^2
41=c^2
sqrt{41}= c
Approximately 6.40312
