What is the best approximation of the length of segment QS? (Note: cos 80° = 0.17)
matrenka [14]

Answer: QS=11.8cm


Step-by-step explanation:

1. You have the following information:

- The lenght of RS is 2 centimeters.

- The angle m∠S=80°.

- Cos80°=0.17

2. Therefore, you can calculate the lenght of the segment QS as following:

cos80=\frac{adjacent}{hypotenuse}

adjacent=2cm\\hypotenuse=QS\\cos80=0.17

3. Substitute values and solve for QS:

0.17=\frac{2cm}{QS}\\QS=\frac{2cm}{0.17} \\QS=11.76cm

4. To the nearest tenth:

QS=11.8cm

Draw a graph that represents the equation y= x-2.
Margaret [11]

Answer:

Check attached graph

Step-by-step explanation:

Given equation is y=x-2.

Now we need to graph the given equation y=x-2.

To graph that we can find two points then join them by a straight line.

We are free to plug any number for x say x=0 and x=2

plug x=0

y=x-2=0-2=-2

Hence first point is (0,-2).

plug x=2

y=x-2=2-2=0

Hence first point is (2,0).

Now graph both points and joint them to get final graph as shown below.
