We are given:  cos theta = 1/3.  Thus, adj side = 1 and hyp = 3.  Using the Pythagorean Theorem to find the length of the opposite side, represented by x.  

1^2 + opp^2 = 3^2, or 1 + x^2 = 9, or x^2 = 8.  Here, x could be either sqrt(8) or -sqrt(8):  sqrt(8) if angle theta is in QI, and -sqrt(8) if in QIV.

Thus, the sine of angle theta could be either sqrt(8)/3 or -sqrt(8)/3.

<h3>What is meant previewing a test?</h3>

In order to find the various problem kinds and their point values during the test preview, you must read the complete test. Mark the questions that you can answer quickly and easily.

The benefits of previewing the test are-

  • You will probably be given credit for the answers even if you accidentally copied them from the scratch paper.
  • Your effort on the scratch paper can earn you some points if a thoughtless mistake causes you to get the answer wrong.
  • If you do make a mistake, it will be simpler to find it when the instructor goes through the test.
  • By doing this, you can avoid making the same errors on your next exam.

Therefore, resolve each issue by re-entering the solution into the equation or performing the opposing operation needed to provide the appropriate response. Do not leave the testing room until the bell has rung or after you have gone over each problem twice.

Yuri [45]

Step-by-step explanation:

This can be put into fractions like this

Say x is the length of the missing dimension

8.5/11 = 10.5/x

Because the 2 drawings are SIMILAR, the ratio of their side lengths has to also be the same

8.5 ÷ 10.5 = 0.8095

11 × 0.8095 = 8.9047

Roung the answer to the nearest tenth

x = 8.9 in

Heidi has 6 pounds of tomatoes from her garden. She used 3/4 of all the tomatoes to make sauce and gave 2/3 of the rest of the t
iren2701 [21]

Answer:

She gives 16 ounces to her neighbor

Step-by-step explanation:

How much did you use to make sauce

6 * 3/4 = 18/4 =9/2 = 4.5  lbs

That leaves 6-4.5 = 1.5 lbs

She give 2/3 of this to her neighbor

1.5 * 2/3

Changing the decimal to a fraction

3/2 * 2/3 = 1

She gives 1  pound to her neighbor, but we want it in ounces

16 ounces equals 1 pound

She gives 16 ounces to her neighbor
