cos(x)= 10/50

cos (x) = \frac{10}{50}

x = 1.36943 \dots + 2 πn, x = 2 π - 1.36943 \dots + 2 πn

Solution steps

cos (x) = \frac{10}{50}

Cancel the common factor:

10

cos (x) = \frac{1}{5}

Apply trig inverse properties

x = arccos (\frac{1}{5}) + 2 πn, x = 2 π - arccos (\frac{1}{5}) + 2 πn

Show solutions in decimal form

x = 1.36943 \dots + 2 πn, x = 2 π - 1.36943 \dots + 2 πn

- 7 tan (x) + 3 = - 3 (3 + tan (x))

csc^{2} (x) + 3 cot^{2} (x) = 1

2 sin^{2} (θ) - sin (θ) - 3 = 0

4 sin (x) cos (x) + 1 = 0

4 sin (x) = 3 csc (x)
