Answer:
<h2>altitude = 5</h2>
Step-by-step explanation:
Look at the picture.
Use the Pythagorean theorem:

<em>subtract 144 from both sides</em>

Answer: 5°
Step-by-step explanation:
You can use a right triangle to solve
Hypotenuse would be the flight path
One leg (opposite) is the tree 65 ft
Tan (Θ) = opposite/ adjacent = 65/750
Θ = arctan (65/750)
Θ = 5°
Let's first find the slope. This is (y_2 - y_1)/(x_2 - x_1), where (x_1, y_1) and (x_2, y_2) are points.
For this problem, our slope is (0 - 2)/(3 - 0) = -2/3.
We can now use the point-slope formula to find the equation of our line:
(y - y_1) = m(x - x_1)
(y - 2) = -2/3(x - 0)
y - 2 = (-2/3)x
y = (-2/3)x + 2
The equation of our line is
