Answer:

B.50

Step-by-step explanation:

The two angles form a right angle ( indicated by the little square )

Right angles have a measure of 90 degrees

Hence, x + 10 + 30 = 90

( Note that we just created an equation that we can use to solve for x )

We now solve for x using the equation we created

x + 10 + 30 = 90

Combine like terms

x + 40 = 90

Subtract 40 from both sides

x = 50

-15x= -30

x=2

the amount of 75 octane is 2 gallons
the amount of 90 octane is 13 gallons

Hope this helps.
