Answer: 9/14
Step-by-step explanation: 4+3+2/4+5+3+2 = 9/14
The elevation of the plane is 3600 ft
Let
- h = elevation of plane,
- d = distance from Marsha's house to spot on ground below plane = 3600 feet and
- Ф = angle of elevation of plane = 45°
From the triangle, we have the trigonometric ratio
tanФ = h/D
<h3>Elevation of the plane</h3>
Making h subject of the formula, we have
h = DtanФ
substituting the values of the variables into the equation, we have
h = DtanФ
h = 3600 ft × tan45°
h = 3600 ft × 1
h = 3600 ft
So, the elevation of the plane is 3600 ft
