Answer:
6). Option (B)
7). Option (C)
Step-by-step explanation:
6) Property of a triangle :
"Sum of all interior angles is 180°"
(x + 2)° + (2x + 2)° + (2x - 1)° = 180°
5x + 3 = 180°
5x = 177°
x = [tex]\frac{177}{5}=35.4[/tex]
(x + 2)° = 37.4°
(2x - 1)° = 69.8°
(2x + 2)° = 72.8°
Option (B) is the answer.
7). (4x + 2)° + (2x + 1)° + (x - 1)° = 180°
7x + 2 = 180°
7x = 178°
x = [tex]\frac{178}{7}= 25.43[/tex]
(4x + 2)° = 103.7
(2x + 1)° = 51.9°
(x - 1)° = 24.4°
Option (C) will be the answer.
