The length of the hypotenuse is 40 mm.
<u>Step-by-step explanation:</u>
<em>We can solve for 'a' using Pythagoras theorem. Let's solve it.</em>
-
10² = 5² + a²
- => 100 = 25 + a²
- => a² = 75
- => a = 8.660
- => a = 8.7
Hence, the length of the hypotenuse is 8.7 m.

20 mysteries. Add 20% and 30% to get 50%. Then rewrite 50% as 50/100. Next multiply 50/100 by 40 to get 2,000/100.The last thing to do is simplify to get 20 and subtract 20 from 40 to get 20 mysteries.
