Ответ:
x = 135°
Step-by-step explanation:
this is a 6-sided polygon so to find the sum of the interior angles you use this formula: (n - 2)·180° where 'n' are the number of sides
(6 - 2)·180° = 4(180)° = 720°
2 right angles = 180°
4x + 180 = 720
4x = 540
x = 135°
Ответ:
5(y - 3) - 2 (3 - 2y) = 6
5(3 - 3) - 2(3 - 2 × 3) = 6
The equation works!
Y = 3
Great work!
