Answer:

$x\degree = 75\degree$

Step-by-step explanation:

Property used: <em>An exterior angle of a triangle is equal to the sum of the opposite interior angles.</em>

$= > 62\degree + (x + 13)\degree = 2x\degree \\ \\ = > 62\degree + x\degree + 13\degree = 2x\degree \\ \\ = > 75\degree = 2x\degree - x\degree \\ \\ = > 75\degree = x\degree \\ \\ = > x\degree = 75\degree$
