Solution of problem: An electric post was broken by a strong typhoon .it rmed a right triangle with the ground.If a broken part makes an angle of 25 degrees with other part and the topmost part of the post which on the ground is 40 feet from the base ,how tall was the post?

Answer 1

A = 90-25 = 65o.

tanA = Y/X.
Y = X*tanA = 40*tan65 = 85.8 Ft.

Z = X/cosA = 40/cos65 = 94.6 Ft. = hyp.

h = Y + Z = 85.8 + 94.6 = 180.4 Ft. = Ht. of post.
