Answer 1

Answer:

Mark me as brainliest ..

Step-by-step explanation:

Let line x+1=y intersect x axis at A

and other line at B, also another line intersect x axis at C,

Now for y=x+1, slope=1, so, ∠BAC=tan−1(1)=45∘

and for y=3x−1 slope=3, so, ∠BAC=tan−1(3)=60∘

Using the external angle property in triangle ABC we get,

∠BAC=∠ABC=∠BCX⟹45∘+θ=60∘⟹θ=15∘
