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) is****the 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) is****the measure of angle K could also be 151°**
