Hope this helps:)

You're told that tan(θ) is positive, but

tan(θ) = sin(θ)/cos(θ)

and you're also told that sec(θ) = 1/cos(θ) = -3. So if cos(θ) is negative, sin(θ) must also be negative. In turn, both sec(θ) = 1/cos(θ) and csc(θ) = 1/sin(θ) are also negative.

Now, recall the Pythagorean identity,

cos²(θ) + sin²(θ) = 1

Multiply through both sides by 1/cos²(θ) to get an alternate form of the identity,

1 + tan²(θ) = sec²(θ)

Solve for tan(θ) (which we know is positive):

tan(θ) = √(sec²(θ) - 1) = 2√2

Right away, we get

cot(θ) = 1/tan²(θ) = 1/(2√2) = √2/4

Since sec(θ) = -3, it follows that cos(θ) = -1/3.

Then

tan(θ) = sin(θ)/cos(θ) ==> sin(θ) = 2√2 × (-1/3) = -2√2/3

and so

csc(θ) = 1/sin(θ) = -3/(2√2)

The LCD for the fractions 1/3, 3/4, 5/32, and 8/9 is

liraira [26]

we know that

The LCD is the LCM (least common multiple) of all the denominators.

we have

$1/3, 3/4, 5/32, 8/9$

$3=3^{1} \\ 4=2^{2} \\ 32=2^{5} \\ 9=3^{2}$

$LCM=2^{5} *3^{2} \\ LCM=32*9\\ LCM=288$

The LCM of $3, 4, 32, 9$ is $288$ ,

which is the multiple of the highest power of prime factors from all of the given numbers

therefore

the answer is

$288$

The perimeter of triangle rxa is 24. if rx= 4 and ra= 11, find xp and pa

BigorU [14]

Answer:
PA = 6.6 units
XP = 2.4 units

Explanation:
1- We are given that:
perimeter of RXA = 24 units
RX = 4
RA = 11
This means that:
XA = 24 - 4 - 11 = 9 units

2- For XA:
XA = XP + PA
XA = 9 units
This means that :
XP + PA = 9 units
XP = 9 - PA

3- Triangle angle bisector theorem:
"In a triangle, the angle bisector divides the opposite side into two segments that are proportional to the other two sides"

Applying this to the given triangle, we can set the ratio as follows:
$\frac{XP}{PA} = \frac{XR}{AR}$

We have:
XP = 9 - PA
RX = 4
RA = 11

4- Substitute with the givens in the above ratio and solve for PA as follows:
$\frac{9-PA}{PA} = \frac{4}{11}$

11(9-PA) = 4(PA)
99 - 11PA = 4PA
99 = 15PA
PA = 99/15
PA = 6.6 units

5- Substitute to get XP as follows:
XP = 9 - PA
XP = 9 - 6.6
XP = 2.4 units

Hope this helps :)
