What is the equation in point-slope form of a line that passes through the points (7, −8)(7, −8) and (−4, 6)(−4, 6) ? y−6=−1411(x+4)y−6=−1411(x+4) y+6=−1411(x−4)y+6=−1411(x−4) y−6=−23(x+4)y−6=−23(x+4) y+6=−23(x−4)

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°
