Question

points A, B, C and D lie on a line segment in that order. If AB=CD=9. If the ratio of AB to BC is 1:3, what is the length of AD?

Answer 1

Explanation:

So as the usual we can see that

Ab=9 and cd=9

And we can get bc by

ration reading 1

So AB:BC=1:3

SO we said that AB is 9 so we have to multiply The ratio by 9:9 we can see that the ratio will be AB:CD=9:27 the main thing here is we have got the BC which Is 27

So AD means the sum of all Points

AB+BC+CD=AD

9+27+9=AD

AD=45

Thanks in Advance
