Answer:
Yoy answer is x=10
Step-by-step explanation:
We already know what ∠GEF is 23°
so you would have to create an equation like this [tex]23+(5x+1)=7x+4[/tex]
you add 23+1=24 and get [tex]5x+24=7x+4[/tex] subtract 5x on both sides
[tex]24=2x+4[/tex] subtract 4 on both sides
[tex]20=2x[/tex] divide 2 x=10
∠DEF=7(10)=70+4=74
∠DEG=5(10)=50+1=51
To check 51+23=74
