Write the equation of the line that is perpendicular to the line y = 2x + 2 and passes through the point (6, 3).

There asking for the equation, and the possible answers are 

y = 2x + 6 y = −one halfx + 3 y = −one halfx + 6 y = 2x + 3

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°
