Answer:
Angle EDC = Angle ADC
(Reflexive property)
ABD ~ ECD because all angles are congruent
If two are congruent, third one has to be as well since total angle is 180 each
Each pencil cost $2.
Explanation: She had $24 before buying the pencils and after she had $10. 24-10=14 so the total she spent on pencils was $14. She bought 7 pencils so you divide 14 by 7 (14/7=2) which equals 2. So each pencil cost $2.
tenths because 42.02 it would be tenths the first decimal is tenths and second is hundreths
The reflected coordinates are (7,4) You can find this out by imagining a point on the left upper side in quadrant 2. Then, when you flip it to quadrant 1, both coordinates are positive!
