4 0

Answer:

-4/3.

Step-by-step explanation:

cos O = 3/5

Using Pythagoras to find the length of the side opposite the angle O:

As the cos of O is adjacent/ hypotenuse, Hypotenuse = 5 , adjacent side = 3 so

opposite side. = sqrt(5^2 - 3^2) = sqrt 16

= 4.

Now the tangent is negative in Q IV so

tan O = opposite / adjacent side = -4/3

Simplify and solve for the given variable. <br>Solve 19x = 3 + 4(x + 6) - 2<br>for X.

Rom4ik [11]

Answer:

5/3

Step-by-step explanation:

19x=3+4(x+6)-2

19x=3+4x+24-2

19x-4x=3+24-2

15x=27-2

15x=25

x=25/15

simplify

x=5/3

Please help, last unit of algebra 2, thankyou!!!!!!!!!!!!

Mumz [18]

Answer:

$\cot \theta = \frac{8}{15} \\\\\sec \theta = \frac{17}{8} \\\\\csc \theta = \frac{17}{15}$

Step-by-step explanation:

$\huge \tan \theta = \frac{15}{8} ...(given) \\ \\ \huge \because \: \cot \theta = \frac{1}{ \tan \theta} \\ \\ \huge \therefore \: \cot \theta = \frac{1}{ \frac{18}{8} } \\ \\ \huge \therefore \: \cot \theta = \frac{8}{15} \\ \\ also \\ \huge \sec \theta = \frac{17}{8} \\$
