cos(x)= 32/50

cos (x) = \frac{32}{50}

x = 0.87629 \dots + 2 πn, x = 2 π - 0.87629 \dots + 2 πn

Solution steps

cos (x) = \frac{32}{50}

Cancel the common factor:

2

cos (x) = \frac{16}{25}

Apply trig inverse properties

x = arccos (\frac{16}{25}) + 2 πn, x = 2 π - arccos (\frac{16}{25}) + 2 πn

Show solutions in decimal form

x = 0.87629 \dots + 2 πn, x = 2 π - 0.87629 \dots + 2 πn

tan (\frac{A}{2}) = 1.02

(sin (a) + cos (a))^{2} + (sin (a) + cos (a))^{2} = 2

h = 3 sin (2 x - 1) + 4

sin^{2} (x) + 2 = 3 sin (x)

sin (x + \frac{π}{3}) = \frac{1}{2} cos (x - \frac{π}{6})
