<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)

6) AB = DE (corresponding parts of congruent triangles are equal)
Answer:
No real solution
Step-by-step explanation:
There is no perfect squares in 50
Temp1 = 60
Temp2 = 75
Temp2 - Temp1 = 15
Difference = (Temp2 - Temp1) / Temp1
Difference = 15 / 60 = 1 / 4 = 0.25
Percentage difference = difference * 100% = 0.25 * 100% = 25%
By the way this problem is worded, he spends 75 minutes reading and cleaning, but there seems to be not enough information because the way it is worded, it means he has 75 minutes until he needs to GET READY, not play in the actual game. (40 + 35 = 75).
The answer is 33. First do 3 times 5, 15, then do that -2. 13. 13 plus 4 times 5 is 33 :)
