The value of x is 32.5
Perpendicular lines are two lines that intersect at a 90-degree angle (right angle).
This intersection forms four right angles (90 degrees each). The slopes of perpendicular lines are negative reciprocals of each other; when multiplied together, their product is -1.
We can then say that;
25 + 2x = 90
collect the like terms, we get;
2x = 90 - 25
subtract the value
2x = 65
Divide by the coefficient of x
x = 32.5
