When solving for lengths of sides or angles in triangles, how do you know whether to use Trig Ratios, Sine Law or Cosine Law? If someone would lend a hand it’d be awesome, thanks;)

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950

4+4+2x

or

2x+8
