Here is what the plane would look like if the figure and points were drawn.
Answer:
C. m<1 + m<5 = 180 (reason: they are consecutive angles, and should be congruent)
Answer:
−3a+38
Step-by-step explanation:
i simplified the expression
Answer:
Compare x^2 +y^2-8x-6y=75 with the general circle equation x^2+y^2 -2ax-2by+c=0
-2a =-8 And -2b=-6
a=4 b=3
c=-75
To find the radius use the equation
r^2=a^2+b^2-c
r^2=4^2+ 3^2-(-75)
r^2=25+75=100
r=10(radius is always positive)
Hence the center is (4,3) and radius 10
