The Anwser Is -12 Because He Swam 12 Feet Deep And It Would Not Be The Other Answers Because He Did Not Swim More Down Into The Pool So It Would Be -12
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
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
Answer: The answer is leg(s).
Step-by-step explanation: In a triangle you have two parts, a hypotenuse and 2 legs. The legs are adjacent, or opposite, to the right angle. The hypotenuse is actually the right angle itself.
