Question

If LM = 20 cm, and PQ = 16 cm, what is the length of RM, in centimeters?

Answer 1

RM = 12 cm

Explanation:

`a^(2) + b^(2) = c^(2)`

Assuming 20 is the hypotenuse cus there is no picture:

`a^(2) + 16^(2) = 20^(2)`

`a^(2) +256 = 400`

`a^(2) = 144`

`a=144`

If It's not the hypotenuse:

`16^(2)+ 20^(2) =c^(2)`

`256+400 =c^(2)`

`656=c^(2)`

`c = 25.61249695`

But I find it unlikely that 20 wasn't the hypotenuse so ignore that unless it applies.

Hope this helped. :0)
