106

Step-by-step explanation:

the angles combined equal 180 degrees. so to put it into an equation:

x+10+64=180

x+74=180

x=106

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

it would open into a square depending on the type of envelope i’m not sure about the second part
