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*
If incorrect, my apologies.
Answer:
7/10
Step-by-step explanation:
2/5 + 3/10
Find the LCM of Denominators.
The LCM is 10.
Divide the LCM by the denominator of the first fraction and multiply the result by the numerator. Also do same with the second fraction. Add the results of both fractions and let the lcm be the denominator of the added results.
We have
4 + 3 /10
7/10
Solve x
Substitute -y+6 for x in 3x-4y=-31
3x-4y=-31
3(-y+6)-4y=-31
Simplify both sides of the equation
-7y + 18 = -31
Add -18 to both sides
-7y+18-18=-31-18
7y= -49
Divide both sides by -7
7y/-7= -49/-7
y= 7
Substitute 7 for y in x = -y+6
x= -y+6
x= -7+6
Simplify both sides of the equation
x= -1
Answer : x= -1 and y = 7
I hope that's help and have a great night !
Answer:
10
Step-by-step explanation:
The first step to the question is how much 1/3 is of 180.
A third of 180 is 60 because 60*3 = 180.
Now the important number is 60.
The second step is to find how much 1/6 is of 60.
You can do multiplication or you could do division.
60 divided by 6 is 10.
Therefore, your answer is 10.
Answer: is going to be 36 because all you have to do is multiply something that it multiplyed by 5 to get 180 and you'll get your answer
