The point where two lines meet is known as an angle. The value of x if OA is perpendicular to OC is 30 degrees
What is line geometry?
The point where two lines meet is known as an angle.. From the given diagram;
(180 - 4x) + x = 90
Simplify the result
180 - 3x = 90
Subtract 180 from both sides
-3x = 90 - 180
-3x = -90
Divide both sides by -30
x = 90/3
x =30degrees
Hence the value of x if OA is perpendicular to OC is 30 degrees
