Given: angles ABC is a right angle and angles DEF is a right angle. Prove: All right angles are congruent by showing that angles ABC congruent angles DEF.

What are the missing reasons in the steps of the proof?

A: Def. of right angle, def. of congruent, def. of equal, def. of 90°

B: Identity prop., reflexive prop., subtitution prop., symmetric prop.

C: Def. of congruent angles, def. of equal angles, substitution prop., symmetric prop.

don't know what that says sorry i can't you

step-by-step explanation:

idk what it says

answer: i don't understand. what are the options

step-by-step explanation:

the final price would be 29.6925

step-by-step explanation:

39.59 minus 25% equals 29.6925

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
