If 2tan^2 x-sec x=1 which of the following are true? select all that apply
a. sec x=1
b. sec x=3
c. tan x=3
d. tan x=-1
e. sec x=3/2

option e) secx = 3/2

Step-by-step explanation:

Given that

Let us write tan square in terms of sec square using the identity that

Substitute for tan square

Equate each factor to 0 to get

sec x = -1 or sec x = 1.5

When sec x =-1, x =180 and tanx =0

Hence correct options is only

option e) secx = 3/2

ask the math teacher she or he would know lol.

step-by-step explanation:

you meant circumference well the answer is:

17.27876 miles

area is 23.7583

the radius is 2.75 miles

hope this hmu if needed.
