Question

one end of a ladder of 26 m length touches the top of a building and its other is at a distance of 10 m from the base of the building find the height of the building

Answer 1

By Pythagoras theorem,
26²=10²+hieght²
676-100=height²
576=hieght²
√576=hieght²
24= hieght

Answer 2

adj* =26*-10*
adj*=576
so ,adj=√576
adj=24
