Answer:
Find the value of x, if 8,x, x, 50 are in proportion.
If a,b,c and d are in proportion then we have a/b = c/d
Now we need to find the value of x given if 8, x, x, 50 are in proportion.
So we have 8/x = x/50
Or x x x = 8 x 50
Or x^2 = 400
Or x = ±√400
Or x = ± 20
Therefore the value of x will be + 20 or - 20
