9514 1404 393

  160

Step-by-step explanation:

The problem statement tells us ...

  (# in museum) = 4 × (# waiting)

  (# in museum) = 4 × 40 . . . . . . . . . . . . the number waiting is 40

  # in museum = 160

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
