cos(θ)= 2/(sqrt(3.38^2+2^2))

Solution

cos (θ) = \frac{2}{3.3 8 ^{2} + 2 ^{2}}

Solution

θ = 1.03649 \dots + 2 πn, θ = 2 π - 1.03649 \dots + 2 πn

Solution steps

cos (θ) = \frac{2}{3.3 8 ^{2} + 2 ^{2}}

Simplify

\frac{2}{3.3 8 ^{2} + 2 ^{2}} : \frac{2 15.4244}{15.4244}

Apply trig inverse properties

θ = arccos (\frac{2 15.4244}{15.4244}) + 2 πn, θ = 2 π - arccos (\frac{2 15.4244}{15.4244}) + 2 πn
