There’s a problem with chair B. In order to fix it, the mechanics need to know the angle formed at the center of the ferris whee
dybincka [34]

Answer:

60 degrees

Step-by-step explanation:

The wheel is a circunference, so it has a total of 360 degrees. As we have 12 chairs evenly spaced, this 360 degrees will also be divided evenly, so the angle between each pair of chairs is equal to 360 / 12 = 30 degrees.

As we want the angle between chairs B and D, we have two spaces between chairs (the space between B and C and the space between C and D), so the angle is 2 * 30 = 60 degrees

Verify that the equation is an identity sec X - COS X= sin x tan x To verify the identity, start with the more complicatad side
notka56 [123]

You have the following equation:

secx - cosx = sinxtanx

In order to verify the previous identity, you show that the left side is equal to the right side. You proceed as follow:

secx - cosx = 1/cosx - cosx

to get the same denominators multiply by cosx/cosx in the second term:

1/cosx - cos²x/cosx

add the homogeneus fractions:

(1 - cos²x)/cosx

use the identity sin²x + cos²x = 1 => 1 - cos²x = sin²x

sin²x/cosx

write sin²x as sinxsinx

(sinx)(sinx/cosx)

separate the expression into two factors by replacing sinx/cosx = tanx

(sinx)(tanx)

Then, the given equation is an identity and it has been demonstrated that

secx - cosx = sinx tanx
