Answer:
D. 2
Step-by-step explanation:
M(0,2b)
N(2a,0)
Then the midpoint P coordinates are
P\left(\dfrac{2a+0}{2},\dfrac{0+2b}{2}\right)\Rightarrow P(a,b)
Use distance formula to find OP and MN:
OP=\sqrt{(a-0)^2+(b-0)^2}=\sqrt{a^2+b^2}\\ \\MN=\sqrt{(2a-0)^2+(2b-0)^2}=\sqrt{4a^2+4b^2}=2\sqrt{a^2+b^2}
So,
MN=2OP
or
OP=1/2 MN

Answer:
So AC = 25
Step-by-step explanation:
ABC = LMN
That means AB = LM
BC = MN
AC = LN
We know AB = 41 MN = 38 and LN = 25
AB = LM = 41
BC = MN=38
AC = LN=25
So AC = 25
