Answer:
c
Step-by-step explanation:
x²+y²+4x+6y=0
compare with x²+y²+2gx+2fy+c=0
centre is (-g,-f)=(-2,-3)
radius=√(g²+f²-c)=√((-2)²+(-3)²-0)=√13
Answer:
The angle measure for angle c is 138 degrees
Answer:
37 degree
Step-by-step explanation:
AB = 180 it is a straight line
ACD = 90 degree
DE+ DCB are complimentary angles they add up to 90 they dont need to be next to each other.
DE = 53 deg
DCB = 90-53= 37 degree
g = 37 and F is its vertical angle as they share the same corner point and lay opposite each other and each have same angle 37 degree.
Answer:
B and D
Step-by-step explanation:
This must be a six sided figure
A. 15 x 15. This would be area
B. 6 x 15. This is the sum of six sides of 15
C. 15 + 6. This is the sum of 2 sides of different length
D. 15 + 15 + 15 + 15 + 15 + 15. This is the sum of six sides of length 15
Answer:
x=3
Step-by-step explanation:
5x+6=21
5x=15
x=3
