Step-by-step explanation:
Answer: b = 69
The slashes mean the opposite angles are the same. This is and isosceles triangle, which mean two sides are the same and one is not.
A triangle = 180
We know one angle is 42 and the other two angles are the same.
Subtract 42 from 180
180 - 42 = 138
Now the 138 is going to two sides but we know they are equal so we can divide 138 by 2
138 divided by 2 = 69
So b = 69
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%
Answer:

Step-by-step explanation:
