If the interior angles of hexagon are 107°, 2x°, 150°, 95°, (2x-15)° and 123°, find x.
- \(57\frac{1}{2}^{\circ}\)
-
\(65^{\circ}\)
- \(106^{\circ}\)
- \(120^{\circ}\)
The correct answer is: B
Explanation
Sum of interior angle in a hexagon = (6 - 2) x 180°
= 720°
\(\therefore\) 107° + 2x° + 150° + 95° + (2x - 15)° + 123° = 720°
460 + 4x = 720 \(\implies\) 4x = 720 - 460
4x = 260° \(\implies\) x = 65°
