Answer:

area = 148.72 ft^2

Step-by-step explanation:

height =sin 55 x 16.5

height =0.8192 x 16.5

height = 13.52

area=0.5 x base x height

area = 0.5 x 22 x 13.52

area = 148.72 ft^2

Answer:

[tex]16\frac{1}{2}=16.5[/tex]

S is the area of this triangle, we have:

[tex]S=\frac{1}{2}16,5. 22.sin55[/tex] = 148,676
