Answer:
32m + 24n
Step-by-step explanation:
Distribute the 8 to the other terms.
8(4m + 3n)
32m + 24n
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.
To solve this, divide the numbers 11 and 20 . . .
11 ÷ 20 = 0.55 ←
You can check your work by multiplying 20 and 0.55 to get 11.
0.55 * 20 = 11
<u>Your answer is 0.55</u>
<u>11/20 as a decimal is 0.55</u>
