<u>Part</u><u> </u><u>(</u><u>i</u><u>)</u>
1) AB is perpendicular to BC, ED is perpendicular to CD, BC = CD (given)
2) Angles ABC and CDE are right angles (perpendicular lines form right angles)
3) Angles ABC and CDE are equal (all right angles are equal)
4) Angles ACB and DCE are equal (vertical angles are equal)
5) Triangles ABC and EDC are congruent (ASA)
<u>Part</u><u> </u><u>(</u><u>ii</u><u>)</u>
6) AB = DE (corresponding parts of congruent triangles are equal)
First combine like terms:
14d+-2d=12d
Then do -84 divided by 12 = -7
D= -7

Answer:
4 hours 48 minutes
Step-by-step explanation:
Right now, in this problem the whole set comprises of a single day and you know that there are 24 hours in a day.
In order to solver the problem,you have to draw a number line of length 24 and then separate it into 5 equal parts. (because there are total five brothers)
or simply, just divide 24 by 5.
= 24/5 => 4
hours
lets convert 4/5 hour to minutes, as you know there are 60 minutes in one hour.
therefore, 4/5 x 60= 48 minutes.
Answer: Each brother will spend 4 hours watching the puppy in single day, which is likewise 4 hours 48 minutes
