cos(x)=(48.4)/(54.5)

cos (x) = \frac{48.4}{54.5}

x = 0.47765 \dots + 2 πn, x = 2 π - 0.47765 \dots + 2 πn

Solution steps

cos (x) = \frac{48.4}{54.5}

Apply trig inverse properties

x = arccos (\frac{48.4}{54.5}) + 2 πn, x = 2 π - arccos (\frac{48.4}{54.5}) + 2 πn

Show solutions in decimal form

x = 0.47765 \dots + 2 πn, x = 2 π - 0.47765 \dots + 2 πn

(sin (x^{3} + 2 x - 1)) a = 1

cos (θ) = - \frac{7}{10}

cot (b) = \frac{tan ( b ) cot ( b )}{csc ( b )}

h, f = tan (x) tan (h) x

cos (x) + 2 sin (x) + 3 = 0
