Answer:

115

Step-by-step explanation:

By interior angle sum postulate of a quadrilateral.

$3x \degree + 45 \degree = 360 \degree \\ \\ 3x \degree = 360 \degree -45 \degree \\ \\ 3x \degree = 315 \degree \\ \\ x \degree = \frac{315 \degree }{3} \\ \\ x \degree = 105 \degree \\ \\ x = 105$

Prove identity tan 3x−tan 2x−tanx = tan 3xtan 2xtanx

NeX [460]

Tan ( a + b ) = [ tan a + tan b ] / [ 1 - (tan a)*(tan b) ];

let be a = 2x and b = x;

=> tan 3x = [ tan 2x + tan x ] / [ 1 - (tan 2x)*(tan x) ] => (tan 3x)*[ 1 - (tan 2x)*(tan x) ] =

tan 2x + tan x => tan3x - tan 3xtan 2xtanx = tan 2x + tan x => <span> tan 3x−tan 2x−tanx = tan 3xtan 2xtanx.</span><span />
