Answer:
2
Step-by-step explanation:
7x - 2x = 13 - 3
5x = 10
x = 2
The given convex polygon has 7 sides
Hence its sum of interior angles is given by the formula , (number of sides-2)x180°
=> (7-2) x 180°
=> 5 x 180°
=> 900°
The sum of all angles must be equal to 900°
The given six angles are :
139°,126°,106°,129°,141°,112° , x°
=> 139+126+106+129+141+112+x = 900°
=> 753 + x = 900
=> x = 900-753
=> x = 147°
Hence 147° is the required answer.
Answer:
x>125
