What is the measure of ∠a? a. 45° b. 15° c. 60° d.) cannot be determined

Triangle has 3 equal sides so it is equilateral triangle.

<A = <B = <C = 60 degrees

Answer

C. 60°

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
