The value of x in the diagram is 125
Since P and Q are cut by the traversal R , (2x + 40) and (3x - 85) are alternate angles
Now we have;
- (2x + 40) = (3x - 85) (Alternate angles are equal)
Collect like terms
2x - 3x = -85 - 40
-x = -125
divide both sides by -1
x = 125
Therefore, the value of x is 125
