You need to find the width of the stream. You cannot measure the width directly, so you draw a diagram showing lengths that you

can measure. Your diagram contains two similar triangles, one in the stream and one on land. Use the diagram to find the width of the stream.

What is the value of x?
Agata [3.3K]

Answer:

x=68

Step-by-step explanation:

We begin by setting up as a proportion. 99.2 and 112 ft are across from each other so we can put those as our numerators. Additionally 62 and (x+2) ft are across from each other so we can put those as denominators. Now we can set up our proportion and begin to cross multiply:

99.2/62 = 112/(x+2) is our equation. It might help you see it clearly to write it out as fractions. From here, we cross multiply.

When we do that, we get x=68

A kite is being flown at a 45 angle. The string of the kite is 120 feet long. How high is the kite above the point at which the
MrRissso [65]

Answer: The height of the kite above the point at which the string is held is 120\sqrt{2} feet.

Step-by-step explanation:

Given : A kite is being flown at 45^{\circ} . The string of the kite is 120 feet long.  

Let AB denote the string of kite and AC be the height of the kite above the point at which the string is held.

Now, in right Δ ABC

\sin45^{\circ}=\frac{AC}{AB}\\\Rightarrow\ \frac{1}{\sqrt{2}}=\frac{AC}{120}\\\Rightarrow\ AC=120\sqrt{2}

hence, The height of the kite above the point at which the string is held is 120\sqrt{2} feet.

If f(x) = x^2 – 25 and g(x) = x – 5, what is the domain of (f/g)(x)
daser333 [38]

a water tank holds 280 gallons. two percent of the water is lost at stream. how many gallons remain to be used ?
mart [117]
If you would like to know how many gallons remain to be used, you can do this using the following steps:

lost: 2% of 280 gallons = 2% * 280 gallons = 2/100 * 280 = 5.6 gallons

280 gallons - 5.6 gallons = 274.4 gallons

The correct result would be 274.4 gallons.
