cos(180-x)=-cosX

$\\ \rm\Rrightarrow tan^2135-cosec^260=-xcos45.sin45.cot60$

$\\ \rm\Rrightarrow (-1)^2-(\dfrac{2}{\sqrt{3}})^2=-\dfrac{x}{\sqrt{2}}\times \dfrac{1}{\sqrt{2}}\times \dfrac{1}{\sqrt{3}}$

$\\ \rm\Rrightarrow 1-\dfrac{4}{3}=\dfrac{-x}{2\sqrt{3}}$

$\\ \rm\Rrightarrow \dfrac{3-4}{3}=\dfrac{-x}{2\sqrt{3}}$

$\\ \rm\Rrightarrow \dfrac{-1}{3}=\dfrac{-x}{2\sqrt{3}}$

$\\ \rm\Rrightarrow \dfrac{1}{\sqrt{3}}=\dfrac{x}{2}$

$\\ \rm\Rrightarrow x=\dfrac{2}{\sqrt{3}}$

Solve for x please anyone?

Katen [24]

Answer: x=11

Step-by-step explanation:

The lines are parallel, which you can tell by the two arrows. 4x-8 is a corresponding angle to 3x+3, meaning they are congruent.

4x-8 = 3x+3

x=11
