By the equations according to the <em>cylindrical</em> system of coordinates, the equation for a helix are x = 8 · cos (2π · t /T), y = 8 · sin (2π · t /T) and z = 6 · (t/T).
<h3>How to derive the equations of a helix in cylindrical form</h3>
According to the <em>cylindrical</em> system of coordinates, helix can be described by the following equations:
Radius
x = r · cos (2π · t /T) (1)
y = r · sin (2π · t /T) (2)
Height
z = H · (t/T) (3)
Where T is the period of one <em>complete</em> revolution.
If we know that r = 8 and H = 6, then the equations for the helix is:
x = 8 · cos (2π · t /T)
y = 8 · sin (2π · t /T)
z = 6 · (t/T)

We can make a proportion here, 8/16, where the proportion is x/y. We can make another proportion that says 16/y, and y would be 32, because twice the number of x is y.
The slope is the difference of the y-coordinates divided by the difference of the x-coordinates, which gives us 5/2, or 2.5
Answer:
A = 45
B = 90
C = 45
Step-by-step explanation:
Isosceles triangles have two side that are the same and two angles that are the same. Since one angle, B, is a right angle, 90°, that means the other 2 angles, A & C, added together equal 90°.
Divide 90 by 2 and you 45° for both A and C.
X=2
