see the attached figure to better understand the problem
Step 
in the triangle ABC
<u>Find the distance AC</u>
we know that
In the right triangle ABC

solve for AC


substitute the values


Step 
in the triangle DEF
<u>Find the distance DF</u>
we know that
In the right triangle DEF

solve for DF


substitute the values


Step 
Find the value of x
we know that
the value of x is the difference between AC and DF


round to the nearest meter-------> 
therefore
<u>the answer is</u>
The value of x is 
Answer:
Final answer is approx x=-0.66.
Step-by-step explanation:
Given equation is
.
Now we need to solve equation
and round to the nearest hundredth.






Now use calculator to calculate log values, we get:

Round to the nearest hundredth.
Hence final answer is approx x=-0.66.
Answer:
three hours and 36 mins
Step-by-step explanation:
Answer:
$120
Step-by-step explanation:
They have raised $780 and need to raise $900.
(Total amount they need to raise) - (total amount they raised) = (how much more they need to collect)
$900 - $780 = $120
