Which terms are like terms?
17j3, 92m, 32j2, 12j, 10m2, 42j, 18j3, and 6m4
choose all answers that are correct.
a.
12j and 42j
b.
17j3, 32j2, 12j, 42j, and 18j3
c.
17j3 and 18j3
d.
10m2 and 6m4

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°
