When you reflect a point across the line y = x, the x-coordinate and y-coordinate change places. This gives you such reflection rule:
From the diagram:
L(3,1), M(4,3), N(5,3) and P(4,1).
Using the reflection rule, you can find coordinates of image points:
L'(1,3), M'(3,4), N'(3,5) and P'(1,4).
As you can see, these are coordinates of vertices of the figure C.
Answer: correct choice is option 3 - figure C.
Answer: 5:40 am
Step-by-step explanation:
The train reached the station at 9:15 am after having travelled for 3 hrs 35 minutes.
The time the train departed from Riya's hometown was the time it arrived in Mumbai station less the time taken to travel:
= 9:15 - 3:35
First deduct the 3 hours:
= 9:15 - 3
= 6 : 15 am
Remove the 35 minutes by first removing the 15 minutes
= 6:15 - 15
= 6:00 am
Then remove the rest of the 35 minutes which is 20 minutes:
= 6:00 - 20 minutes
= 5:40 am
Answer:
9. the measure of DEF is 103°
10. the measure of DEG is 77°
11. 90°
Step-by-step explanation:
it's pretty simple, just take into consideration that the final measure of all the angles of a triangle must be 180°
