Solve 19cos θ = 5 cos θ + 14 for all values of θ if θ is measured in radians.

Ф=xπ, x={0,+∞}

Step-by-step explanation:

be 19cosФ=5cosФ+14 → 19cosФ-5cosФ-14 → 14cosФ-14=0 → cosФ=1

then,  values for which cosФ=1 are Ф=0º=360º=720º, but the values of Ф  must be radians, so Ф=xπ, where x∈Z, not including the negative numbers,

x={0,1,2,3,∞}

Note: π≅3.141592

when calculating the values, it must be done in radian mode

i'm pretty sure it would take 20 hours because it's half the men so you multiply the number of hours it takes by 2
