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

LuckyWell [14K]

Answer:

RM = 12 cm

Step-by-step 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)

7+x=60 or 60-7=53
