The answer is: Two possible solutions which are (0.53, 37.19)
Explanation:
Given:
A = 30°
<span>a = 20 </span>
<span>b = 16 </span>
Now use the law of Cosines:
a² = b² + c² - 2bc*cos(A)
Plug in the values:
20² = 16² + c² - (2*(16)*c*cos(30))
<span>400 = 256 + c² - 32c(0.866) </span>
<span>400 = 256 + c² - 27.71c </span>
<span>c² - 27.71c = 400 - 256 </span>
<span>c² - 27.71c = 144 </span>
<span>c² - 27.71c + 191.96 = 144 + 191.96 </span>
<span>(c - 18.86)² = 335.96 </span>
<span>c - 18.86 = √336.95 </span>
<span>c - 18.86 = ± 18.33 </span>
<span>c = 18.86 ± 18.33 </span>
<span>If c = 18.86 + 18.33, then </span><span>c = 37.19 </span>
<span>If c = 18.86 - 18.33, then </span><span>c = 0.53 </span>
<span>c = (0.53, 37.19) Two solutions!</span>

Step-by-step explanation:
<span>One ounce is equal to 28.35 grams. convert 16 ounces to grams round your answer to the nearest tenth.
Solution:
1 ounces = 28.35 grams
thus the number of grams in 16 ounces will be:
16 ounces=(16/1</span>×28.35<span>) grams
=453.6 grams</span>
