lukranit [14]3 years ago
8 0

Answer:

x=6

y=-3

Step-by-step explanation:

<em><u>solve for x-</u></em>

-4x+8y=-24 replace y with 0

-4x+8(0)=-24

-4x=-24 divide by -4 on both sides

x=6

<u><em>Solve for y-</em></u>

-4x+8y=-24 replace x with 0

-4(0)+8y=-24

8y=-24 divide by 8 from both sides

y=-3

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
