Aset of bleachers 20 feet long rises from the ground at an angle of 33°. what is the length of the bleachers along the ground? round to the nearest tenth.

Based on my understanding, 20 feet serves as the hypotenuse of the triangle created when the bleacher rises from the ground at an angle of 33°.

sin θ = opposite / hypotenuse
cos θ = adjacent / hypotenuse
tan θ = opposite / adjacent

sin 33° = opposite / 20 ft
sin 33° x 20ft = opposite 
0.544 x 20 = opposite
10.89 ft = opposite

cos 33° = adjacent / hypotenuse
cos 33° x 20 ft = adjacent
0.839 x 20 = adjacent
16.77 ft = adjacent

I think the the length of the bleachers along the ground is the value of the adjacent which is 16.77 ft.
