This scenario sets up a pair of similar right triangles. the smaller triangle had height 5 and base 6,5. the larger had height x (height of the tower, which we want to measure). and base of 177 the proportion is then x/177 = 5/6.5, or
6.5x = 5*177
6.5x=885
x=136.15
answer is 136 feet

  P(W|B) = 0.58

Step-by-step explanation:

The conditional probability formula tells you ...

  P(W | B) = P(W&B) / P(B)

  = 0.29/.050

  = 0.58
