Question

it's a class 10 th advance maths. plz ans this right answer and explain me how to do it.

Answer 1

The gradient of a line = Change in y/ Change in x


Gradient  = Δy/Δx

We notice that Tan∅ = Opposite/Adjacent = Δy/Δx


So;

Tan ∅ = 1/√3


and 


∅ =  Tan Inverse 1/√3 = 30 degrees


The line makes 30 degrees with the x-axis

Answer 2

Answer:

Step-by-step explanation:

The gradient of a line = Change in y/ Change in x

Gradient = Δy/Δx

We notice that Tan∅ = Opposite/Adjacent = Δy/Δx

So;

Tan ∅ = 1/√3

and

∅ = Tan Inverse 1/√3 = 30 degrees

The line makes 30 degrees with the x-axis
