Step-by-step explanation:
He is incorrect because if you substitute x for 37 you will get the equation 8×37+200. 8×37=296 +200= 496. Since it is not greater or equal to 500 the inequality is not true.
Answer:
The answer to your question is: y = 80°
Step-by-step explanation:
The sum of the internal angles in a polygon is = 180°(n - 2)
= 180° (6 - 2)
= 180(4)
= 720°
y° + y° + 2(2y -20) + 2(2y -20) = 720
2y° + 4(2y -20) = 720
2y° + 8y -80 = 720
10y = 720 + 80
10 y = 800
y = 800 / 10
y = 80°
2y - 20 = 2(80) -20 = 160 -20 = 140
80° + 80° * 140 + 140 + 140 + 140 = 720°
