Select the correct answer. What is the general form of the equation of a circle with center at (a, b) and radius of length m?

x2 + y2 − 2ax − 2by + (a2 + b2 − m2) = 0

x2 + y2 + 2ax + 2by + (a2 + b2 − m2) = 0

x2 + y2 − 2ax − 2by + (a + b − m2) = 0

x2 + y2 + 2ax + 2by + a2 + b2 = -m2

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  ≈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°
