Help Please: Two boats start their journey from the same point A and travel along directions AC and AD, as shown below: What is the distance, CD, between the boats? 230.9ft 284.3ft 115.5ft 173.2ft

  230.9 ft

Step-by-step explanation:

The side ratios of a 30°-60°-90° triangle are 1 : √3 : 2

In ∆ABC, BC = AB/√3 ≈ 115.47 ft

In ∆ABD, BD = AB√3 ≈ 346.41 ft

Then the length CD is ...

  346.41 ft -115.47 ft = 230.94 ft

The distance CD is about 230.9 ft.

connie < felicia < stew

step-by-step explanation:

stew:

we need to find the slope

m = (y2-y1)/ (x2-x1)

    = (2650-795)/(10-3)

    = 1855/7

connie:

we need to find the slope

m = (y2-y1)/ (x2-x1)

we have two points (0,0) and (4,800)

m = (800-0)/(4-0)

  m = 800/4
