Trig question save mee simplify each expression to one trig function or number

sec(x)

Step-by-step explanation:

tan x * sinx + cos x

Tan x = sin x/ cos x

Replace tan x in the equation

sinx /cosx * sin x + cos x

sin^2 x / cos x + cos x

We know sin^2 x = 1 -cos^2 x

Replace sin^2 with 1 -cos ^2 x

(1 -cos^2 x) / cos x  + cos

Distribute the denominator

1 /cos x - cos x + cos x

Combine like terms

1/cos x

sec x

answer would be 8.64 or s = 11π/4 inches

step-by-step explanation:

s = r θ  

where s = arc length  

r = radius = 3 inches  

θ = central angle in radians = ( π /180)*165  

s = 3(π/180)*165  

= 8.64 inches
