Solve the right triangle shown in the figure BC = 1.6in< A=48.8 C =90
yKpoI14uk [10]
Drawing a diagram to represent the information you've given, the only angle we are missing is B.  We can find that by subtracting the two we're given from 180:
180 - 90 - 48.8 = 41.2
<em>m</em>∠<em>B</em> = 41.2°.
We can use the angles and the one side we're given to find the remaining sides.  Since we do not know the length of the hypotenuse, AB, we cannot use sine or cosine.  We must use tangent (the ratio for tangent is opposite/adjacent):
\tan 41.2 = \frac{x}{1.6}
Multiply both sides by 1.6:
1.6 \tan 41.2 = x&#10;\\ 3.67 = x
This is the length of side AC, which is opposite to angle B.
To find the length of AB we can use the Pythagorean Theorem:
(1.6)^2+(3.67)^2=c^2&#10;\\ 2.56+13.4689=c^2&#10;\\ 16.0289=c^2&#10;\\ \sqrt{16.0289} = \sqrt{c^2}&#10;\\ 4=c
The length of side AC, the hypotenuse, is 4 inches.

Brooke went to the hardware store and bought 20 identical copper pipes. When Brooke lined up the pipes end-to-end, the line was
Sergio039 [100]

Answer: 5cm

Step-by-step explanation:

First and foremost, we should note that

1 meter = 100 centimeters

Therefore, since Brooke went to the hardware store and bought 20 identical copper pipes and their total length is 1 meter long which is 100cm, the length of each pipe will be the title length of the Pipe divided by the number of pipes. This will be:

= 100 / 20

= 5cm each.

Each pipe is 5cm long.

Answer:

  • 12 quarts

Step-by-step explanation:

Let the amount of pineapple juice be x quarts, the concentration of juice is as following equation:

  • 4*0.2 + x*0.6 = (4 + x)*0.5
  • 0.8 + 0.6x = 2 + 0.5x
  • 0.6x - 0.5x = 2 - 0.8
  • 0.1x = 1.2
  • x = 12
