The answer is C because since the answer is 4 and if u look at c it would equal to 4.
X = 30 I think as angle on straight line = 180 so 180-103 = 77 , 30+43 = 73 , 77+73 = 150 , 180-150= 30 , then opposite angles are the same so therefore x = 30 degrees
Answer:
See below
Step-by-step explanation:
(-12)²=144 while -(12²)=-144
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%
