Answer:
The answer to your question is below
Step-by-step explanation:
1) The triangles are similar by the AA postulate so use proportions to find x.
x/207 = 170/90
solve for x
x = 207(170/90)
x = 207(1.89)
x = 391 ft
2) These triangles are similar so use proportions to solve it
x/138 = (x + 60)/207
207x = 138(x + 60)
207x = 138x + 8280
207x - 138x = 8280
69x = 8280
x = 8280/69
x = 120
Answer:
<u>12,240 meters</u>
Step-by-step explanation:
Since sound travels 340 meters per second, you multiply 340 by 36 seconds, and get the answer of <u>12,240 meters.</u>
Standard form becuase the 70 is not spelled out
