Answer:
[tex]\angle x=46^o[/tex]
Step-by-step explanation:
we know that
An isosceles triangle has two equal sides and two equal angles
so
The triangle of the figure is an isosceles triangle because has two equal sides
therefore
Remember that the sum of the interior angles in a triangle must be equal to 180 degrees
so
[tex]2\angle x+88^o=180^o[/tex]
Solve for angle x
[tex]2\angle x=180^o-88^o[/tex]
[tex]2\angle x=92^o[/tex]
[tex]\angle x=46^o[/tex]
