Please help! I suck at math ;-;
ale4655 [162]

Answer:

x=80

Step-by-step explanation:

because all lines intersect at point E, we could safety say they are equal. therefore, we can also say that angles aef+def=ceg+beg.

we already know what ceg+beg is; 160 and we also know what def is, which is 80.

we set up an equation plugging it in. we will say ceg=x.

x+80=160, subtract 80 on both sides and you get x=80!

hoped this helped :)
