cos(θ)= 7/(3sqrt(17))

cos (θ) = \frac{7}{3 17}

θ = 0.96925 \dots + 2 πn, θ = 2 π - 0.96925 \dots + 2 πn

Solution steps

cos (θ) = \frac{7}{3 17}

Simplify

\frac{7}{3 17} : \frac{7 17}{51}

Apply trig inverse properties

θ = arccos (\frac{7 17}{51}) + 2 πn, θ = 2 π - arccos (\frac{7 17}{51}) + 2 πn

Show solutions in decimal form

θ = 0.96925 \dots + 2 πn, θ = 2 π - 0.96925 \dots + 2 πn

sin (A) - 0.1 \cdot cos (A) = \frac{6.94}{9.8}

t, s = 2 arctan (t)

\frac{cos ( x )}{tan ( x )} = \frac{3}{2}

cos (2 x) + 5 cos (x) = 3

sin (θ) = \frac{207.91 \cdot sin ( 31.7697 7 ^{\circ} )}{238.99}
