Answer:
acute
Step-by-step explanation:
obtuse is over 90°
acute I less that 90°
and right is exactly 90°
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

Let's say H represents the number of Hip-hop songs and P the number of Pop songs:
The first equation that describes the number of songs: H + P = 25
The second equation is for the price: 2H + 3P = 60
If you solve the system of equations you get P = 10 and H = 15
If e-the initial hight of the tree, and the function imply some brackets like
f(x)=30/(1+29e-0.5x) then
for every
the rate of growth is negative, the maximum growth per unit of time would be 30ft
If
then
so the tree couldn't be 2ft tall initially
if the brackets are something like
f(x)=30:(1+29e)-0.5x then the results may differ
