Answer:
hypotenuse is 22.47 m
Step-by-step explanation:
The length of both legs of a right angle triangle are 8m and 21 m
We need to find the hypotenuse
To find hypotenuse we use Pythagorean theorem
Hypotenuse is AC and other two legs are AB and BC
[tex]AC^2 = AB^2 + BC^2[/tex]
Hypotenuse ^2 = 8^2 + 21^2
hypotenuse = [tex]\sqrt{8^2 + 21^2}[/tex]
= [tex]\sqrt{64 + 441}[/tex]
= [tex]\sqrt{505}[/tex]
= 22.47
So the length of the hypotenuse is 22.47 m
