WHAT IS THE VAULE OF X

The answer is x=56, so the first thing I did is that I equaled all of that to 180, because a triangle equals to 180 degrees.

So here are the steps.

x+x-31+x+43=180

3x+12=180 Add all the like terms to get this

-12 -12. then subtract 12 on both sides

3x= 168.

÷3 ÷3

x=56

then divide 3 on both sides to get the total answers.

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°
