Find how far the car can travel on one gallon of gas, by dividing total miles by number of gallons:
105 miles / 7 gallons = 15 miles per gallon.
Now multiply that by the number of gallons to find total miles:
15 miles per gallon x 9 gallons = 135 total miles.
The answer is C. since a triangle has to have a total of 180 degrees, you have to add both of the degrees of both the angles. 60 + 60= 120.
180-120=60
Your last angle is 60 degrees.
