Use the trigonometric ratio tan (which uses the opposite and adjacent sides)
tan60=35/x
which is
x=35/tan60
which equals 20.2
20.2 ft

It is pretty long, hope you understand
x+y+z=6
+
2x-y+z=3
-------------
3x+2z=9
->3x=9-2z (1)
3x-z=0
3x=z (2)
From (1)+(2)-> z=9-2z
solve for z
-3z=9
z=-3 (3)
plug (3) in (2)
->3x=-3
->x=-1 (4)
Plug (3) and (4) in <span>x+y+z=6
</span>-3+y+(-3)=6
solve for y
y-6=6
->y=12
Answer:
x=-1
y=12
z=-3
The equation to find a circumference is
(c = circumference, r = radius, d = diameter)
c = 2r · π
So we need to find the radius.
A radius is half of the diameter, so
12/2 = 6
Now put the value in the equation and solve.
c = 2 · 6 · π
c = 12 · π
c = 37.7
The answer is <span>37.7

Answer:
X=7
Step-by-step explanation:
2 + |x-4| = 5
2 + x -4 = 5
2 + x = 5 + 4
2 + x = 9
x = 9 - 2
x=7
