Find the center and radius for the circle by the equations: x2 + y2 + 5x - y + 2 = 0.

lord [1]

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)

ΔJKL has j = 7, k = 11, and m∠J = 18°. Complete the statements to determine all possible measures of angle K. Triangle JKL meets

gladu [14]

We know that
Applying the law of sines

$\frac{k}{sin K} = \frac{j}{sin J} \\ \\ \frac{11}{sin K} = \frac{7}{sin 18} \\ \\ 11*sin 18=7*sin K \\ \\ sin K= \frac{11}{7} *sin 18 \\ \\ sin K=0.4856$

$K=arcsin(0.4856)$
$K=29$ °

so
∠J=18°
∠K=29°
∠L=180-(18+29)=133°

the answer Part a) is
the measure of angle K is ≈29°

Part b) the measure of angle K could also be
(180-29)=151°
so
∠J=18°
∠K=151°
∠L=180-(18+151)=11°

the answer Part b) is
the measure of angle K could also be 151°
