The total of interior angles of a polygon is found using the formula 180 x (n-2) where n is the number of sides.
The above figure has 7 sides, so the total of the interior angles is: 180 x (7-2) = 180 x 5 = 900 degrees.
Find X:
Total all angles: 2x+4x+4x+4x+4x+2x+10x = 900
30x = 900
X = 900/30
x = 30
Angle A = 2x = 2*30 = 60 degrees
The answer is A.
C. 84*

The percentage of 37% of the sum of the numbers 27.6 and 15.9 will be
The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.
The percentage is also called the indicating hundredths. Thus, 2% is two-hundredth, which means 2%=2/100=0.02.
The first method →
Find the sum of two numbers,
27.6 + 15.9 = 43.5
37% of 43.5 will be as,
0.37 x 43.5 = 16.095
The second method →
Find the 37% of 27.6 as
0.37 x 27.6 = 10.212
Find the 37% of 15.9 as
0.37 x 15.9 = 5.883
Add both numbers as
10.212 + 5.883 = 16.095
The easiest method is method 1 because it is fewer in steps.
Hence "The percentage of 37% of the sum of the numbers 27.6 and 15.9 will be 16.095.

Answer: 1 hour
Step-by-step explanation:
1st trip = 4mph
12 mi / 4 mi
12 mi = 3 hrs
2nd trip = 6 mph
12 mi / 6 mi
12 mi = 2 hrs
3hrs - 2 hrs = 1 hr
The number of liters of water in container A holds that container B is 9484 liters.
It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.
It is given that:
Container B holds 2,391 liters of water. Together, Container A and Container B hold 11,875 liters of water.
Let x be the number of liters of water container A hold than container B
x = 11875 - 2391
x = 9484 liters
Thus, the number of liters of water in container A holds that container B is 9484 liters.
