Answer:
option A is the answer.
Because the sum of two smaller sides of a traingle should be larger then third side. This condition is only fulfilled in option A.
15+25= 40 which is more then 38.
while in other options it's either equal or smaller then third side.
-8x/-8 - 8y/-8=0
x-8y/-8=0
x+y=0
the answer is x+y=0
Well what does the question ask you
