Question

if angle EFG and angle GFH are a linear pair, m angle EFG=4n+15, and m angle GFH =5n+39. what are m angle EFG and m angle GFH

Answer 1

EFG is 71 degrees, GFH is 109 degrees

Explanation:

Linear pairs add up to 180 degrees

4n+15+(5n+39)=180

Add Like Terms: 9n+54=180

Subtract 54 from both sides: 9n=126

Divide 9 from both sides: n=14

Substitute 14 for n: GFH=5(14)+39= 109

EFG=4(14)+15 = 71
