Question

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

A: 19
B: 23
C: 10
D: 90

Answer 1

Hi there!

We know that each angle is equal to 90 degrees, so all we have to do is set 9y equal to 90 and solve!

WORK:
90 = 9y
y = 10

ANSWER:
C - 10

Hope this helps!! :)
If there's anything else that I can help you with, please let me know!

Answer 2

Answer: C: 10

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
`9y=90^(\circ)`

Dividing 9 on both sides of above equation, we get

`y=10^(\circ)`

Hence, the value of y = 10
