In the diagram below, AC is perpendicular to BD. Find the value of Y.
A: 19
B: 23
C: 10
D: 90

Answer: C: 10
Step-by-step explanation:
Given: In the diagram, AC is perpendicular to BD.
We know that the angle mage by perpendicular lines is 90°.
Then if 9y is representing the angle made by line segments AC and BD.
then [tex]9y=90^{\circ}[/tex]
Dividing 9 on both sides of above equation, we get
[tex]y=10^{\circ}[/tex]
Hence, the value of y = 10
