Answer:
<h2><u><em>
60°</em></u></h2>
Step-by-step explanation:
it looks like an isosceles triangle, 2 equal side and 2 equal angles (F&E)
the sum of the interior angles in a triangle is 180°, and FH is 180°.
180 - 120 = 60° (angle G)
now we know that it is an equilateral triangle, so Y and 2x are 60°
(3 * 60 = 180°)
-------------------------------
or
180 - 60 = 120
120 : 2 = 60°
