Question

What is the tan if x?

Answer 1

`\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`
