Question

The measures of the angles of a quadrilateral are (x+2)°, (x+2)°, (x – 13)° , and x + 29°; x = ____.

85°
40°
340°
90°

Answer 1

The answer is that x=85

Answer 2

x = 85

Explanation:

The sum of the measures of the angles of a quadrilateral is 360°.

(x+2)° + (x+2)° + (x – 13)° + (x + 29)° = 360°

4x + 20 = 360

4x = 340

x = 85
