Answer

assume that abd has a measure of 105°

assign a variable and write an equation that will you determine the measure of dbc

the measure of dbc is

you should know that a line is 180°

we can assign DBC the variable "x"

x = 180 minus the measure of angle ABD

so x = 180 - 105 which equals 75

the answer is 75°

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

answer: 2530

hope this
