In the diagram below, AC is perpendicular to BD. Find the value of N.

timurjin [86]

Hi there!

In order to find the value of N, we'll need to set the value of the angle containing the variable n equal to 90. This is because in perpendicular lines, all angles are equal to 90.

WORK:
5n - 25 = 90
5n = 115
n = 23
