The sum of all angles of a triangle is equal to 180°
On a isosceles triangle, the base angles are the same.
We add them together 56° + 56° = 112°
To know X, we subtract 112° from the total
180° - 112° = 68°
X = 68°
OR as an equation
56 + 56 + x = 180
112 + x = 180
x = 180 - 112
x = 68
1, 4, 9, 4, 10, 8, 42
Put this into order.
1, 4, 4, 8, 10, 42
It would most definitely not be the mode, because there is an outlier, and it wouldn't be the median, because once again, there is an outlier.
So, that leaves you with the mean.
The mean would measure this the best because it'll represent it the best. It is also the only one that'll fully make sense.
So, your answer is : The mean.

Answer:
X=x−4
Step-by-step explanation:
2(x−3)+X=5x−2(x+5)
Use the distributive property to multiply 2 by x−3.
2x−6+X=5x−2(x+5)
Use the distributive property to multiply −2 by x+5.
2x−6+X=5x−2x−10
Combine 5x and −2x to get 3x.
2x−6+X=3x−10
Subtract 2x from both sides.
−6+X=3x−10−2x
Combine 3x and −2x to get x.
−6+X=x−10
Add 6 to both sides.
X=x−10+6
Add −10 and 6 to get −4.
X=x−4
The answer to this problem is false due to the number 2 not being used in the equation.
Answer:
3x+2/4>-20
3x+2>-80
3x>-80-2
3x>-82
x>-82/3
Also simplified to, x>-27 1/3
