Question

Let tri.ABC be a right angle triangle with right angle B and denote angle LBAC be 0. Draw a altitude from the right angle to side AC, then from this point draw an altitude to side BC, continue in this manner and draw an infinite sequence of altitudes in the triangle. Find the total length of all these altitudes in terms of |AB| and 0.

Answer 1

angle LBAC be 0 What does it mean?

Answer 2

Draw a altitude from the right angle to side AC, then from this point draw an altitude to side BC, continue in this manner..

There 2 ways to go, which one?

Answer 3

L = angle and 0= theta.
I don't know about the second one.
That what's the question states. I hope this clears it
