Answer:
second option
Step-by-step explanation:
To get the percent of increase, we will follow these steps:
1- get the difference between the two numbers:
difference = 1.8 - 1.2 = 0.6
2- divide the difference from step one by the original number (the number before the increase) and then multiply the quotient by 100 to get the percent as follows:
% of increase = (0.6 / 1.2) * 100 = 50%
Based on the above calculations, the percent of increase in the amount of iron is 50%

Here, Cos (60°) = BC/AB = <u>a/12 units</u>

Answer:

Step-by-step explanation:
<u>Triangle Congruence</u>
Given triangle ABC is congruent to triangle DEC, then it's true that angle ABC is congruent to angle DEC.
The figure shows that:


Those angles are congruent, or have the same measure, thus:
