In a quadrilateral, two angles are x°, two angles are (3x+8)°. What is x and the measures of the angles?

1. Step-by-step explanation:

   the sum of all angles in any quadrilateral is 360°.

   so,

   x + x + 3x + 8 + 3x + 8 = 360

   8x + 16 = 360

   8x = 344

   x = 344/8 = 43°

   3x + 8 = 3×43 + 8 = 129 + 8 = 137°

   so, the angles are

   43°

   137°

   43°

   137°
