One interior angle of a regular pentagon measures (4X + 8) degrees. Find X.

25

Step-by-step explanation:

In order to find the value of the interior angle of a regular polygon, the equation is ((n−2)180)/n where n is the number of sides of the regular polygon.

For pentagon, it's has five sides

The formula is ((n−2)180)/n

((5−2)180)/5 = 3 ×180/5 = 540/5 = 108

Since from the question one interior angle measures (4X + 8)

so 4x+8= 108

4x = 108-8 = 100

x = 100/4 =25

plzplzplzplzplz mark brainliest i need it.

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
