Answer: 57.8512 feet (approx)
Step-by-step explanation:
Let h be the height of the stone face.
The angle of elevation from one sight to the bottom of face that is 750 feet far from the base of the mountain is 33°
⇒ The distance of the base of the stone face from the base of the mountain = 
The angle of elevation from another sight to the top of face is 36° that is also 750 feet away from the base of the mountain,
Therefore,
The distance of the top of the stone face from the base of the mountain = (h + 487.055694898) feet
By the trigonometry,
Therefore, the height of the stone face is 57.8512 feet (approx).
Answer I am sorry I just need points
Step-by-step explanation:
If you want to multiply 2 binomials, take each term in the first set of parentheses and multiply it to every term in the second set of parentheses:
3h*(2h+m) = 3h^2+3hm
-2m*(2h+m) = -4hm-2m^2
Combine like terms: (3hm-4hm)
3h^2-hm-2m^2
Hello from MrBillDoesMath!
Answer:
a. 2
b. - (1/2)
Discussion:
a. The slope of the line y = 2x +3 is 2. A line parallel to this lien has the same slope, that is, 2.
b. Two lines are perpendicular if the products of their slopes is -1. Sine the slope of the original line is 2 the slope. "m", of the perpendicular line is given by
2*m = -1
or
m = -1/2
Thank you,

-1.42-2.9=1.48
1.424-(-2.9)=1.424+2.9=4.324
-1.424-(-2.9)-0.576=-1.424+2.9-0.576=3.748
I hope it helps!
