Question

a ladder 15meters long just reaches the top of a vertical wall.If the laddermakes an angle of 60degrees with wall.Find the height of the wall.(Trignometry problem)

Answer 1

Answer:

15root3/2

Step-by-step explanation:

sin60= perpendicular (height of wall) ÷ hypotenuse (ladder)

sin60= root3/2 = x/15

X = 15root3/2 ans.
