X2+5x+y2-y=-2
X2+2*5x2+(5/2)^2-(5/2)^2+y2-2*y/2+(1/2)^2-(1/2)^2=-2
(x+5/2)^2+(y-1/2)^2-13/2=-2
(x+5/2)^2+(y-1/2)^2=9/2
So centre =(-5/2,1/2)
Radius=(9/2)^(1/2)
Answer:
-49
Step-by-step explanation:
you can first divide both sides by -6
so
-12 = y+37
so y = -12-37 = -49
We know that
Applying the law of sines



°
so
∠J=18°
∠K=29°
∠L=180-(18+29)=133°
the answer Part a) isthe measure of angle K is<span>
≈29°Part b) </span><span>the measure of angle K could also be
(180-29)=151</span>°
so
∠J=18°
∠K=151°
∠L=180-(18+151)=11°
the answer Part b) isthe measure of angle K could also be 151°
