The circumcenter of a right angled triangle is midpoint of the hypotenuse side.
Determine the midpoint of the hypotenuse.
For y coordinate,
So, circumcenter of triangle is,
Answer:
red= about 324°
blue= 360°
Green=about 144°
Step-by-step explanation:
Answer:
y=x-3
Step-by-step explanation:
slope=4+2/-5-1=-1
perpendicular slope= negative reciprical=1
y=x+b
midpoint on perpendicular bisector= (-5+1/2, 4-2/2)=(-2,1)
substitution-2=1+b, b=-3
y=x-3
Answer: she has 17 CDs now.
Step-by-step explanation:
The total number of CDs that Chen had initially is 17.
She gives 2 to her brother. This means that she would be having
17 - 2 = 15
She buys 4 more. It means that she would be having
15 + 4 = 19
Her brother gives her 1. So the number that she has is
19 + 1 = 20
she gives 3 to her best friend. Therefore, the number of CDs that Chen has now is
20 - 3 = 17
None of the answers are correct. The correct answer would be x=(P-25)/2
