m<AOC=7x-2, m<DOC= 2x+8,m<EOD=27
WHY ARE ALL OF THESE ANSWERS WRONG WTH
You have to add all the three angles to get the straight angle of 180 degrees
Then you get as an equation, 7x-2+2x+8+27=180
Then you simplify and you get, 9x+33=180
Bring 33 to the other side and you get, 9x=147
Finally you solve for x and you get 16 and 1/2
All the other answers given are incorrect
This is terrible, which answer is right ðŸ˜.
m<AOC=7x-2, m<DOC=2x+8, m<EOD=27 find the value of X
What is the question?
m<AOC=7x-2, m<DOC= 2x+8,m<EOD=27
m�ÚAOC = 7x - 2, m�ÚDOC = 2x + 8, m�ÚEOD = 27 help me find the value of x
2 1/3
To find the value of x and the measures of angles AOC, DOC, and EOD, we can use the fact that the sum of the measures of angles in a triangle is always 180 degrees.
We are given three angles:
m<AOC = 7x - 2
m<DOC = 2x + 8
m<EOD = 27
We can set up an equation to represent the sum of these angles:
m<AOC + m<DOC + m<EOD = 180
Substituting the given values, we have:
(7x - 2) + (2x + 8) + 27 = 180
Simplifying the equation:
7x - 2 + 2x + 8 + 27 = 180
9x + 33 = 180
9x = 180 - 33
9x = 147
x = 147/9
x = 16.33 (rounded to two decimal places)
Now we can find the measures of the angles:
m<AOC = 7x - 2 = 7(16.33) - 2 = 114.31 degrees
m<DOC = 2x + 8 = 2(16.33) + 8 = 40.66 degrees
m<EOD = 27 degrees
Therefore, the measure of angle AOC is approximately 114.31 degrees, the measure of angle DOC is approximately 40.66 degrees, and the measure of angle EOD is 27 degrees.
7x-2+2x+8=27
combine:
9x+6=27
Get x alone:
9x=21
Divide:
x=21/9
reduce:
