Since a triangle's angles add to be 180 degrees, you need to find the measure of the third angle.
180-55-65= 60 degrees
____________________________________
The equation would be 2x+30=60
2x=30
x=15
Cost per gallon of gasoline = $3.95 per gallon.
Total number of gallons of gasoline Mr.Endo buys = 13.6 gallons.
We need to find the total cost of 13.6 gallons of gasoline.
<em>In order to find the total cost of 13.6 gallons of gasoline, we need to multiply it by cost of each gallon of gasoline.</em>
Therefore, cost of 13.6 gallons of gasoline = 13.6 × 3.95
On multiplying 13.6 by 3.95, we get 53.72.
<h3>Therefore, Mr.Endo spend a total $ 53.72 on gasoline.</h3>
