Answer:
Yes
Step-by-step explanation:
6(-1-4)-30(-1) can be simplified into 6(-5)+30 which becomes -30+30, and then 0.
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

Answer:
c = 50
Step-by-step explanation:
Using the Pythagorean Theorem:
Plug in the values of a = 14, and b = 48
Subtract the 18 from the 78 then multiply both sides by -1, then divide by 5.
If the entire angle is equal to 55 degrees than JL would equal 29
