Hey, there!!
Let's simply work with it,
60° + 2x° + (2x+12)° = 180° { being a linear pair}.
or, 72° + 4x = 180°
4x = 180° - 70°
Therefore, the value of x is 27°.
Now,
2x° = (2×27)°= 54°
(2x+12)° = 2×27°+12°= 66°.
(x+2)= 27+ 2= 29°
Now, The left angle is 27°.
Therefore, The answer is option A.

Answer:
325 miles
Step-by-step explanation:
$20 for each day
5 days
$0.30 for each mile
20(5) + 0.3x = 197.5
100 + 0.3x = 197.5
100 - 100 + 0.3x = 197.5 - 100
0.3x = 97.5
x = 325
