The vertical component of a vector is equal to its horizontal component. What is the angle made by the vector with x-axis

Let the vector is $\overrightarrow{\mathrm{A}}$
Vertical component of $\overrightarrow{\mathrm{A}}=\mathrm{Asin}\mathrm{\theta }$
Horizontal component of $\overrightarrow{\mathrm{A}}=\mathrm{Acos}\mathrm{\theta }$
When θ is the angle with x-axis
Given $\mathrm{Asin}\mathrm{\theta }=\mathrm{Acos}\mathrm{\theta }$,
$\begin{array}{l}\Rightarrow \frac{\sin \mathrm{\theta }}{\cos \mathrm{\theta }}=1\\ \Rightarrow \mathrm{Tan}\mathrm{\theta }=1\\ \therefore \mathrm{\theta }={45}^{\circ }\end{array}$
