Ah, subtracting polynomials.
The answer requires you to find the difference of and .
Then, just put everything together.
So, the answer would be choice c.
Answer: m∠EFG=83°
m∠GFH =97°
Step-by-step explanation:
Given : ∠EFG and ∠GFH are a linear pair.
m∠EFG=3n+23, and m∠GFH=4n+17.
We know that linear pair of angles added up to 180 degrees.
i.e
Now, m∠EFG=(3n+23)°= (3(20)+23)°=(60+23)°=83°
m∠GFH =(4n+17)°=(4(20)+17)°=(80+17)°=97°
