Solution steps

sec (\frac{θ}{5}) = 7

Apply trig inverse properties

sec (\frac{θ}{5}) = 7

General solutions for

sec (\frac{θ}{5}) = 7

sec (x) = a \Rightarrow x = arcsec (a) + 2 πn, x = 2 π - arcsec (a) + 2 πn

\frac{θ}{5} = arcsec (7) + 2 πn, \frac{θ}{5} = 2 π - arcsec (7) + 2 πn

\frac{θ}{5} = arcsec (7) + 2 πn, \frac{θ}{5} = 2 π - arcsec (7) + 2 πn

Solve

\frac{θ}{5} = arcsec (7) + 2 πn : θ = 5 arcsec (7) + 10 πn

\frac{θ}{5} = arcsec (7) + 2 πn

Multiply both sides by

5

\frac{θ}{5} = arcsec (7) + 2 πn

Multiply both sides by

5

\frac{5 θ}{5} = 5 arcsec (7) + 5 \cdot 2 πn

Simplify

\frac{5 θ}{5} = 5 arcsec (7) + 5 \cdot 2 πn

Simplify

\frac{5 θ}{5} : θ

\frac{5 θ}{5}

Divide the numbers:

\frac{5}{5} = 1

= θ

Simplify

5 arcsec (7) + 5 \cdot 2 πn : 5 arcsec (7) + 10 πn

5 arcsec (7) + 5 \cdot 2 πn

Multiply the numbers:

5 \cdot 2 = 10

= 5 arcsec (7) + 10 πn

θ = 5 arcsec (7) + 10 πn

θ = 5 arcsec (7) + 10 πn

θ = 5 arcsec (7) + 10 πn

Solve

\frac{θ}{5} = 2 π - arcsec (7) + 2 πn : θ = 10 π - 5 arcsec (7) + 10 πn

\frac{θ}{5} = 2 π - arcsec (7) + 2 πn

Multiply both sides by

5

\frac{θ}{5} = 2 π - arcsec (7) + 2 πn

Multiply both sides by

5

\frac{5 θ}{5} = 5 \cdot 2 π - 5 arcsec (7) + 5 \cdot 2 πn

Simplify

\frac{5 θ}{5} = 5 \cdot 2 π - 5 arcsec (7) + 5 \cdot 2 πn

Simplify

\frac{5 θ}{5} : θ

\frac{5 θ}{5}

Divide the numbers:

\frac{5}{5} = 1

= θ

Simplify

5 \cdot 2 π - 5 arcsec (7) + 5 \cdot 2 πn : 10 π - 5 arcsec (7) + 10 πn

5 \cdot 2 π - 5 arcsec (7) + 5 \cdot 2 πn

Multiply the numbers:

5 \cdot 2 = 10

= 10 π - 5 arcsec (7) + 10 πn

θ = 10 π - 5 arcsec (7) + 10 πn

θ = 10 π - 5 arcsec (7) + 10 πn

θ = 10 π - 5 arcsec (7) + 10 πn

θ = 5 arcsec (7) + 10 πn, θ = 10 π - 5 arcsec (7) + 10 πn
