Can anyone please find JML

x = 42 ∠JML = 126°

Step-by-step explanation:

A line always adds up to equal 180 degrees. Always remember this, since itll be important. So just add the values of the two angles and make it equal to 180.

3x + 54 = 180

Subtract 54 from both sides to get 3x = 126

Divide both sides by 3 to get x = 42

Now we plug in 42 for x and multiply it by 3. You get an angle of 126

Notice how 126 and 54 add to 180, there is your proof

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°
