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

Hypotenuse ^2 = 8^2 + 21^2
hypotenuse = 
= 
= 
= 22.47
So the length of the hypotenuse is 22.47 m
Answer:
21/143
Step-by-step explanation:
If it was simplified into a decimal it would be .146853
The answer is 5
5x5=25
25x5=125
The answer is 10, because 35 divided by 7 is five, five times 2 is ten.
