please mark me as Brainlist

Answer 2

Answer:

There would be two answers,

In case 1:

If the BC straight line is base and AB is the height then

tan 30°=AB/BC

or,1/√3=AB/15

∴AB=15/√3=5√3

In case 2:

If the AB is base and BC is height then

tan30°=BC/AB

or,1/√3=15/AB

∴AB=15√3

This is your answer, if you give the picture then it would be very easy to understood. Now you choose it.Hope you understand.
