The lengths of two sides of a triangle are 20 cm and 32 cm.
Explain why the third side of the triangle can or cannot have a length of 10 cm

No

Step-by-step explanation:

By the Triangle Inequality Theorem, for sides a, b, and c of a triangle:

a + b > c

a + c > b

b + c > a

Here, we already have two sides of lengths 20 and 32. We want to see if the third side can be 10 cm. Suppose a = 32, b = 20, and c = 10. According to the Triangle Inequality Theorem:

20 + 32 >? 10  ⇒  52 > 10       that's good

32 + 10 >? 20  ⇒  42 > 20       that's also good

20 + 10 >? 32  ⇒  30 > 32       this is false

So, the third side cannot be 10 because that would violate the theorem.

Hope this helps!

  answer:

  write 548 as 500 + 40 + 8. multiply each addend by 5. then add the three products to get 2,740.

they aren't great and cause destruction, idk man
