Answer:
In the given quadrilateral, two angles measure 60° and other two angles measure 120°.
Step-by-step explanation:
As we know sum of all interior angles of a polygon with 'n' sides is,
Sum of interior angles = (n - 2) × 180°
= (4 - 2) × 180° [for a polygon with n = 4]
= 360°
a + a + 2a + 2a = 360°
6a = 360°
x = 60°
Measure of angles = a° = 60°
And angles having measure = 2a° = 2(60)°
= 120°
Therefore, in the given quadrilateral, two angles measure 60° and other two angles measure 120°.
