Answer: 12 refills
Step-by-step explanation:
y = 8.95 + 1.50x
26.95= 8.95 + 1.50x
26.95 - 8.95 = 1.50x
18 = 1.50X
18 / 1.50 = x
X = 12
The situation is represented by a drawing with a right triangle where an airplane is at the top corner, the elevation angle (opposite to the airplane) is 70°, the height (vertical leg) is x, and the adjacent leg (horizontal leg) to the 70° angle is 800.
Then, to find the height x, which is the opposite leg to the angle, you can use the tangent ratio, which is opposite leg divided by adjacent leg:
tan(x) = opposite leg / adjacent leg => tan(70°) = x / 800
Answer: tan(70°) = x / 800
Lines p and q are parallel.
Corresponding angles are congruent.
Each two adjacent angles are supplementary.
Vertical angles are congruent.
Angles 7 and 8 are adjacent, supplementary angles.
m<7 + m<8 = 180
m<7 + 115 = 180
m<7 = 65
Angles 6 and 8 are corresponding angles and congruent.
m<6 = m<8
m<6 = 115
Angles 1 and 6 are vertical angles and congruent.
m<1 = m<6
m<1 = 115
