The leg of a right triangle are 3 units and 10 units. what is the length of the hypotenuse? round your answer to the nearest hundredth

Hey there! This is gonna require the Pythagorean Theorem which is a^2 + b^2 = c^2

a and b in this case are the legs while c is the hypotenuse! So, we can just plug in the numbers we know!

3^2 + 10^2 = c^2

9 + 100 = c^2

109 = c^2

And then take the square root of 109 to get the hypotenuse.

10.4403065089 = c

Since we need to round to the nearest hundredth, though, it would be 10.44

I hope that helps! Feel free to let me know if you have any questions!

1. 0.3 •4 is the same as 4 groups of 0.32. 7•0.8 is the same as 7 groups of 0.83. it increases by 0.5 every time, so 0.5x4 it increases by 0.9 every time, so 0.9x5. 0.9•12=10.86. 0.47•5=2.35i can finish the next ones in a separate post
