Which of the following are valid names for the triangle below? Check all that
apply.

Triangle JKE and Triangle KEJ

Step-by-step explanation:

You have to look at each answer choice for this. For example, for A, it starts at K and then goes to E then to j. That forms a triangle. Whatever answer choice makes a complete triangle is your answer.

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°
