cos(x)=(154)/(212.85)

cos (x) = \frac{154}{212.85}

x = 0.76191 \dots + 2 πn, x = 2 π - 0.76191 \dots + 2 πn

Solution steps

cos (x) = \frac{154}{212.85}

Apply trig inverse properties

x = arccos (\frac{154}{212.85}) + 2 πn, x = 2 π - arccos (\frac{154}{212.85}) + 2 πn

Show solutions in decimal form

x = 0.76191 \dots + 2 πn, x = 2 π - 0.76191 \dots + 2 πn

4 sin^{2} (x) - 2 = 0, 0 \leq x \leq 2 π

csc^{2} (θ) = 7 cot (θ) + 9

cos^{2} (x) + 6 cos (x) = - 3, y = 3

2 sec^{2} (x) - 5 tan (x) = 5

coth (z) = 1
