Find the value of x.

Tatiana [17]

$\large \mathfrak{Solution : }$

The given pair of angles are vertical opposite angle pair so, they are equal. i.e

$(x + 90)\degree = 4x\degree$

$(4x - x) \degree= 90\degree$

$3x\degree = 90\degree$

$x\degree = \dfrac{90\degree}{3\degree}$

$x\degree = 30\degree$
