Help It's a trigonometric equation; Solve
Cos 2/3 x = 2/3

Help please, will mark brainliest.​

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

the answer is c: divide the arc's degree measure by 360°, then multiply by the circumference of the circle.

the answer is b.
