\qquad\qquad\huge\underline{{\sf Answer}}

The given triangle is a right triangle, with one of the acute angle measuring 45°

let's calculate x ~


\qquad \tt \dashrightarrow \:x + 45 + 90 = 180


\qquad \tt \dashrightarrow \:x + 135 = 180


\qquad \tt \dashrightarrow \:x = 180 - 135


\qquad \tt \dashrightarrow \:x = 45 \degree

So, tan x is :


\qquad \tt \dashrightarrow \: \tan(x) = \tan(45 \degree)

[ since x = 45° ]


\qquad \tt \dashrightarrow \: \tan(x) = 1
