cos(θ)=-5/8

cos (θ) = - \frac{5}{8}

θ = 2.24592 \dots + 2 πn, θ = - 2.24592 \dots + 2 πn

Solution steps

cos (θ) = - \frac{5}{8}

Apply trig inverse properties

θ = arccos (- \frac{5}{8}) + 2 πn, θ = - arccos (- \frac{5}{8}) + 2 πn

Show solutions in decimal form

θ = 2.24592 \dots + 2 πn, θ = - 2.24592 \dots + 2 πn

\frac{368.02}{sin ( 6 6 ^{\circ} - x )} = \frac{290}{sin ( 3 8 ^{\circ} )}

cos^{2} (x) sec (x) = 1

tan (x) = \frac{9.3}{7.5}

sin (α) + cos (α) = 1

2 sin (θ) = 3 tan (θ)
