cos(x)=(2.3)/(2.8)

cos (x) = \frac{2.3}{2.8}

x = 0.60688 \dots + 2 πn, x = 2 π - 0.60688 \dots + 2 πn

Degrees

x = 34.77194 \dots^{\circ} + 36 0^{\circ} n, x = 325.22805 \dots^{\circ} + 36 0^{\circ} n

Solution steps

cos (x) = \frac{2.3}{2.8}

Apply trig inverse properties

cos (x) = \frac{2.3}{2.8}

General solutions for

cos (x) = \frac{2.3}{2.8}

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

x = arccos (\frac{2.3}{2.8}) + 2 πn, x = 2 π - arccos (\frac{2.3}{2.8}) + 2 πn

x = arccos (\frac{2.3}{2.8}) + 2 πn, x = 2 π - arccos (\frac{2.3}{2.8}) + 2 πn

Show solutions in decimal form

x = 0.60688 \dots + 2 πn, x = 2 π - 0.60688 \dots + 2 πn
