Question

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

Answer 1

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°
