Question

The angle between the lines xy=0 is
(a) 00
(b) 60°
(c) 90°
(d) 120°​

Answer 1

(c) 90°

Explanation:

Given

`xy = 0`

Required

The angle between the line

First, solve for x and y

`xy = 0`

`x = 0` or
`y=0`

This means that: y axis and x axis

The angle between the two axes is 90 degrees

Hence: (c) is correct
