cos(x)= 50/86

cos (x) = \frac{50}{86}

x = 0.95035 \dots + 2 πn, x = 2 π - 0.95035 \dots + 2 πn

Solution steps

cos (x) = \frac{50}{86}

Cancel the common factor:

2

cos (x) = \frac{25}{43}

Apply trig inverse properties

x = arccos (\frac{25}{43}) + 2 πn, x = 2 π - arccos (\frac{25}{43}) + 2 πn

Show solutions in decimal form

x = 0.95035 \dots + 2 πn, x = 2 π - 0.95035 \dots + 2 πn

cos (θ) = 1.1111111

sin (5 θ) - 17 = - 18

x, z = tan (2 x - y)

cos^{2} (θ) - sin^{2} (θ) = \frac{1}{2}

tan (\frac{x}{9}) = 1
