What does the symbol mean and how do i graph this

That symbol means perpendicular with. In this situation, XY is perpendicular with AB

Step-by-step explanation:

Perpendicular means 2 lines intercept at an angle of 90 degrees

To graph it, it just 2 lines cut (intercept) other at an angle of 90 degrees.

Hope this help you :3

For this case we have that the symbol shown indicates perpendicularity. That is, both expressions are perpendicular.

Example:

The lines are perpendicular when they cross each other at a 90 degree angle. They have slopes that are opposite reciprocals between them. In addition, the perpendicular lines must intersect.

The symbol indicates that they are perpendicular, the expressions form an angle of 90 degrees.

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .
