A boat is heading towards a lighthouse, whose beacon-light is 121 feet above the water. From point A, the boat’s crew measures the angle of elevation to the beacon 5, before they draw closer. They measure the angle of elevation a second time from point BB at some later time to be 10. Find the distance from point A to point B. Round your answer to the nearest foot if necessary.

i not know

step-by-step explanation:

a. 12.5 kg

step-by-step explanation:

f = ma

so

m = f/a = (2500 n)/(200 m/s²) = 12.5 kg

1 n = 1 kg·m/s²

jk it's 20

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.
