Find the value of csc theta ; if cos theta= -1/4 ; 180° < theta < 270°.

can y'all explain your answer for me lol

a.) 4/-15

b.) 4/√15

c.) -4

d.) -4/√15

D

Step-by-step explanation:

Using the trigonometric identities

• cscx =

• sin²x + cos²x = 1

Given

cosΘ = - , 180 < Θ < 270

then Θ is in the third quadrant where sinΘ < 0

sinx = -

sinΘ = - = - = -

Hence

cscΘ = = -

step-by-step explanation:

10/60

step-by-step explanation:

if you divide 10 by 60 the answer is 0.166666 while if you divide or solve the other problems it equals 0.6
