A rt triangle is formed:

hyp. = 15 Ft. = Length of ladder.

Ver. side = 13Ft.

A. sinA / 13 = sin90 / 15.

sinA = 13*sin90 / 15 = 60.07 Deg.

B. The bottom of the ladder can be moved closer to are farther from the

bottom of the wall. But the hor. and

ver. side should always be > 0 to keep

the rt triangle.

CORRECTION: sinA=13*sin90/15 = 0.8666.

A = 60.07 Deg.
