Question

Find the value of the variable and LN if M is between L and M LM=4a,MN=8a,LM=40

Answer 1

LN = 120 and a = 10

Step-by-step explanation:

If we need to find the variable a as, LN is the line and M is the mid point between L and N. So LN = LM + MN

LM = 4a = 40

a = $\frac{40}{4}$ = 10

MN = 8a =  8×10 = 80

So LN = LM + MN

    LN = 40 + 80 = 120
