To find the measure of angle 2, we need to use the fact that the sum of the measures of all four angles around a point is 360 degrees:
Angle 1 + Angle 2 + Angle 3 + Angle 4 = 360
Since angle 1 is given as (10x + 8) degrees and angle 3 is given as (12x - 10) degrees, we can substitute these values into the equation:
(10x + 8) + Angle 2 + (12x - 10) + Angle 4 = 360
Simplifying the equation, we get:
22x + Angle 2 - 2 = 360
Next, we need to determine the measure of angle 4. Since the angles 1 and 3 are adjacent angles and form a linear pair, their sum is 180 degrees:
Angle 1 + Angle 3 = 180
(10x + 8) + (12x - 10) = 180
Simplifying, we get:
22x - 2 = 180
Adding 2 to both sides of the equation, we get:
22x = 182
Dividing both sides by 22, we find the value of x:
x = 182/22 = 8.27
Now, we can substitute the value of x back into the equation to find the measure of angle 2:
22(8.27) + Angle 2 - 2 = 360
182 + Angle 2 - 2 = 360
Combining like terms, we get:
Angle 2 = 178
Therefore, the measure of angle 2 is 178 degrees.

To find the measure of angle 2, we need to use the fact that angles forming a straight line add up to 180 degrees. Since angles 1 and 3 are adjacent and form a straight line, we can write the following equation:
Angle 1 + Angle 3 = 180
Substituting the given expressions for angles 1 and 3, we have:
(10x + 8) + (12x - 10) = 180
Now we can solve for x:
22x - 2 = 180
22x = 182
x = 8.27
To find the measure of angle 2, we substitute the value of x back into the expression for angle 2:
Angle 2 = 10x + 8 = 10(8.27) + 8 = 82.7 + 8 = 90.7
So, the measure of angle 2 is approximately 90.7 degrees. Therefore, the correct answer is 82.
Angle 1 + Angle 3 = 180
Substituting the given expressions for angles 1 and 3, we have:
(10x + 8) + (12x - 10) = 180
Now we can solve for x:
22x - 2 = 180
22x = 182
x = 8.27
To find the measure of angle 2, we substitute the value of x back into the expression for angle 2:
Angle 2 = 10x + 8 = 10(8.27) + 8 = 82.7 + 8 = 90.7
So, the measure of angle 2 is approximately 90.7 degrees. Therefore, the correct answer is 82.
