Answer:
That would be 530.93
Step-by-step explanation:

The value of
.


We know that,

➪ 125° +
+ 30° = 180°
➪
+ 155° = 180°
➪
= 180° - 155°
➪
= 25°
Therefore, the value of
is 25°.
Now, the three angles of the triangle are 125°, 25° and 30°.

✒ 125° + 25° + 30° = 180°
✒ 180° = 180°
✒ L. H. S. = R. H. S.


X = 26 because all the angles in a triangle add up to 180.
According to the equation located here: https://www.1728.org/glwarmng.htm burning one gallon of gasoline produces 19.3 pounds of carbon dioxide.
So, if a car gets 37 miles per gallon and if it travels 400 miles, it will use 10.81 gallons of gasoline and will produce 19.3 * 10.81 = 208.63 pounds of carbon dioxide.
