5/3 a + 100 = 200 - 45 a
Show the work with verification

Step-by-step explanation:

Solving for a:

(equation given)

(minus and add on both sides)

Verification:

To verify the answer, we can substitute the number in:

(left side of the equation)

(right side of the equation)

Since the left side of the equation = right side of the equation when is substituted in the equation, that means our answer is correct.

∴  

Hope this helps :)

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°
