Answer:50°
Step-by-step explanation:
2(x+10)=3x-30
2x+20=3x-30
50°=x
To solve this you need to know Pythagorean theorem.
First, EG is 24, so the halfway points are 12. Knowing Pythagorean triples, you can use 5,12,13 and 12,16,20.
DF = 5+16
DF = 21
If you don't know Pythagorean triples, I have worked it out on the image attached.
Answer:
The correct option is C.
Step-by-step explanation:
From the given figure it is noticed that the coordinates of B are (-5,-7).
If ABC is reflected across x = 1, then




If ABC is reflected across y =-3.




Therefore option C is correct.
I’m not really sure it’s really complicated
