solvefor x,tan(2x)=-(((30+20)/2))/(80)

solve for

x, tan (2 x) = - \frac{( \frac{30 + 20}{2} )}{80}

x = - \frac{0.30288 \dots}{2} + \frac{πn}{2}

Solution steps

tan (2 x) = - \frac{( \frac{30 + 20}{2} )}{80}

Simplify

- \frac{\frac{30 + 20}{2}}{80} : - \frac{5}{16}

Apply trig inverse properties

2 x = arctan (- \frac{5}{16}) + πn

Solve

2 x = arctan (- \frac{5}{16}) + πn : x = - \frac{arctan ( \frac{5}{16} )}{2} + \frac{πn}{2}

x = - \frac{arctan ( \frac{5}{16} )}{2} + \frac{πn}{2}

Show solutions in decimal form

x = - \frac{0.30288 \dots}{2} + \frac{πn}{2}

4 cos (3 θ) = 2

sin (x) = - 0.8176

sin (x) = - 0.342

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

- 15 + 4 cos (x) = - 15 - 22
