Russo is trying to find the area of the lake in his neighborhood. He sees a duck at point C and uses a tape measuring application on his phone to find that the duck is 16 feet from the point of tangency (point B) to the lake, and the point of tangency is 12 feet from the fountain in the center of the lake (point A).

step-by-step explanation:

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
