The distance from the base of the tree from the swing sets is 15 ft
The situation forms a right angle triangle.
The opposite side of the triangle formed is the distance of Emir from the ground.
Therefore, the distance from the base of the tree from the swing sets is the adjacent side of the triangle.
Hence,
tan 33.69 = opposite / adjacent
tan 33.69 = 10 / x
x = 10 / tan 33.69
x = 10 / 0.66666496431
x = 10 / 0.66666496431
x = 15.0000038265
x = 15 ft
