Answer:
y = 97/3
Step-by-step explanation:
12y - 12 = 9y + 85
Subtract: 3y - 12 = 85
Add: 3y = 97
Divide: y = 97/3
Mean= 35.875
Mode= 48
Median= 44
Answer:
17.11 meters
Step-by-step explanation:
You are using trigonometry in this problem.
The height of the flagpole represents the side <u><em>opposite</em></u> the given angle.
The base of the triangle is given as 19 meters and represents the side <u><em>adjacent</em></u> to the given angle.
Out of the main trigonomentric functions (sine, cosine, and tangent), only tangent uses both the opposite and adjacent sides.
Tan(angle) = opposite / adjacent
If we plug in what we know into that equation: <em>tan(42 degrees) = h / 19</em>
This means that <em>your answer = 19 * tan(42) = 17.11</em> meters
3.6 * 10^(-3) is the scientific notation
