I believe your answer is 7 gallons hope i was helpful.
Answer:
48
Step-by-step explanation:
A. 79
The inscribed angle is always 1/2 of the arc.
In this case angle RST is the inscribed angle and arc RT is the arc
The arc is 158
Inscribed angle=.5arc
Inscribed angle=.5(158)
Inscribed angle=79
Ans is (b, a)
although we dont kn the values of a and b,
the x coordinate of c must be same as point D,and y coordinate of C must be same as point B.U can draw a graph to help urself understand better
(-8x^2-5x) - (17x^2+11x)
-25x^2-16x is your answer.
Hope this helps!
