Answer:
x° = 50°
Step-by-step explanation:
x° + 130° = 180° (adjacent angles add up to 180°)
x° = 180° - 130°
x° = 50°
The x-coordinate changes from +3 to -3. The y-coordinate stays the same.
Using it's concept, it is found that the percent increase in the amount of iron per serving was of 50%.
<h3>What is the percentage increase of a value?</h3>
It is given by the increase divided by the initial value, and subtracted by 100%.
In this problem:
- The initial value is of 1.2 mg.
- The increase was of 1.8 mg - 1.2 mg = 0.6 mg.
Hence the percent increase is given by:
P = 0.6/1.2 x 100% = 50%.
