Question

if 1+4tan Tita =4sec tita then cos tita=​

Answer 1

Answer:

sorry I didn't know about the answer

Answer 2

Answer:

x is theta in your case

Step-by-step explanation:

1+4tanx=4secx

1/4=secx-tanx

multiply both side by secx+tanx,

we get:

secx + tanx=4

add secx-tanx and secx + tanx u get

2secx = 17/4

secx = 17/8

cosx=8/17

X is theta ti your case
