Answer:

 \gray{\mathsf{Tan\:A = 1}}

Solution:

 \Large{\boxed{\pink{\mathsf{Given\:that:}}}}

 \green{\mathsf{sin\:A = cos\:A}}

 \Large{\boxed{\blue{\mathsf{We\:know\:that:}}}}

 \large{\mathsf{\frac{sin\:\theta}{cos\:\theta} = tan\:\theta}}

 \large{\mathsf{\implies \therefore \frac{sin\:A}{cos\:A} = tan\:A}}

 \large{\mathsf{\implies \frac{sin\:A}{sin\:A} = tan\:A}}

 \red{\mathsf{[∵\:given\:that: sin\:A = cos\:A] }}

 \large{\mathsf{\implies \therefore \frac{\cancel{sin\:A}}{\cancel{sin\:A}} = tan\:A}}

 \large{\implies{\orange{\therefore tan\:A = 1}}}

 \LARGE{\purple{\boxed{\mathsf{tan\:A = 1}}}}

Step-by-step explanation:

\huge\bf{\mid{\overline{\underline{ANSWER:-}}\mid}}

 \huge\bold{GIVEN:-} \\ \\ \red{ \sin(A) = \cos(A)} \\ \\ dividing \: both \: sides \; by \: \cos(A) \implies \\ \\ \frac{\sin(A)}{\cos(A)} = \frac{\cos(A)}{\cos(A)} \\ \\ \tan(A) = 1........(\frac{\sin(A)}{\cos(A)} = \tan(A) ) \\ \\\huge{\boxed{\boxed{ \blue{ \therefore \tan(A) = 1 }}}}
