Degrees

x = 163.73979 \dots^{\circ} + 36 0^{\circ} n, x = - 163.73979 \dots^{\circ} + 36 0^{\circ} n

Solution steps

cos (x) = - \frac{24}{25}

Apply trig inverse properties

cos (x) = - \frac{24}{25}

General solutions for

cos (x) = - \frac{24}{25}

cos (x) = - a \Rightarrow x = arccos (- a) + 2 πn, x = - arccos (- a) + 2 πn

x = arccos (- \frac{24}{25}) + 2 πn, x = - arccos (- \frac{24}{25}) + 2 πn

x = arccos (- \frac{24}{25}) + 2 πn, x = - arccos (- \frac{24}{25}) + 2 πn
