Question

Cos theta = 7/8 then evaluate 1+sin theta / cos theta

Answer 1

Step-by-step explanation:

hii... your answer is here. .......

let here theta= x.

so.....

cos x= 7/8.

so ....

sin x= √(1-cos^2x)

= √(1-(7/8)^2)

=√(1-49/64)

=√(15/64)

=(√15)/4.

now calculate ... (1+ sin x)/cos x=(1+√15/4)/7/8

=(4+√15)/4×8/7

=(8+2√15)/7.

i hope it's right and helps u.
