9x^+11
I believe this is the answer
The opposite angles of a parallelogram are congruent, so you have to set the values of each angle equal to each other and solve for x.
(10x-19)° = (7x+23)°
-7x -7x
3x-19 = 23
+19 +19
3x = 43
÷3 ÷3
x = 43
Then, substitute the value of x back into the equations.
(10x-19)°
(10(14)-19)°
(140-19)°
121°
(7x+23)°
(7(14)+23)°
(98+23)°
121°
Since K is in the interior of the angle, this means we can use the angle addition postulate.
Angle LMN = (angle LMK) + (Angle KMN)
Angle LMN = (52 degrees) + (12 degrees)
Angle LMN = (52 + 12) degrees
Angle LMN = 64 degreesSee the attached figure for an example of what this could look like.
Answer:
x = - 8
Step-by-step explanation:
Given
6(x - 1) = 9(x + 2) ← distribute parenthesis on both sides
6x - 6 = 9x + 18 ( subtract 9x from both sides )
- 3x - 6 = 18 ( add 6 to both sides )
- 3x = 24 ( divide both sides by - 3 )
x = - 8
