Answer:
889.70 feets
Step-by-step explanation:
From the solution diagram attached :
C = 180 - (40 + 45) = 95°
According to the sine rule :
Sin95 / 1950 = Sin40 / b = Sin 45 / a
1950 sin40 / sin 95 = b = 1248.22 ft
1950 sin 45 / sin 95 = a = 1384.13 ft
Sin 40 = h / 1384.13
h = 1384.13 * sin 40
h = 889.70 feets

-(7x + 4)- 2x + 2 = 52
Distribute the negative sign:
-7x -4 - 2x + 2 = 52
Combine like terms:
-9x - 2 = 52
Add 2 to both sides:
-9x = 54
Divide by -9:
x = -6
Answer: x = -6
Answer:
the square root of 9 is 3
the square root of 25 is 5
the square root of 0.12 is 0.346
Answer:
y=-6x^2-48x-72
Step-by-step explanation:
First we can FOIL.
I've attached an image that explains it.
F: x^2
O: 6x
I: 2x
L: 12
Our equation is now
y=-6(x^2+6x+2x+12)
Combine like terms.
y=-6(x^2+8x+12)
Distribute.
y=-6x^2-48x-72
