Given :
Distance of firefighter from the building, D = 33 feet.
Height of building, h = 45 feet.
To Find :
The angle of elevation of the cat.
Solution :
Let, angle of elevation is Ф.
We know, tan Ф = h/D
tan Ф = 45/33
Ф = tan⁻¹( 45/33 )
Ф = 53.75°
Therefore, angle of elevation is 53.75° .
Hence, this is the required solution.
1. Subtract the second equation from the first and solve for y: 0 - 4y = -20 => y=5
2. Substitute y=5 into one of the equations and solve for x: 4x - 3(5) = -3 => 4x = 12 => x=3
So the solution is (x, y) = (3, 5)
3x + 4y + 2 + 6y 3
3x (4y+6y) (2+3)
3x+ 10y+5
The answer is C.
If we square both sides of the equation, we can rid of the exponent on the right side and add a square root to x + 4
