Given that tan(x)= -4/7, and 270 degrees< x< 360 degrees, what is the exact value of sec(x)

Mathematics

Maurinko [17]3 years ago

Answer:

sec(x) = 1.15

Step-by-step explanation:

We can figure out what x is by using the arctan(x) function:

x = arctan(-\frac{4}{7}) = -29.74

So, now let's figure out the cos(x) as sec(x) is equal to the reciprocal of cos(x):

cos(-29.74) = 0.87

Let's take the reciprocal:

sec(x) = \frac{1}{cos(-29.74)} = 1.15

And that's your answer.

If angle vuw = 4x+6 and wut = 6x+10 what is the measure of wut
Damm [24]

Answer:

C, 38°

Step-by-step explanation:

ray UW is the angle bisector of ∠VUT

--> m∠VUW = m∠WUT = 1/2 m∠VUT

<=> 4x + 6 = 6x - 10

<=> 6 + 10 = 6x - 4x

<=> 2x = 16

<=> x = 8

So, the measure of m∠WUT is: 6x - 10 = 6 . 8 - 10 = 48 - 10 = 38°

Can I have help with 42?
Sphinxa [80]
#42.
14n - 32 = 22
add 32 to both sides
14n - 32 + 32 = 22 + 32
simplify
14n = 54
divide both sides by 14
14n/14 = 54/14
simplify
n = 3 12/14
n = 3 6/7 or n = 3.857
