It's looking for the measures
m<F + m<G = 180°
(4x)° + (8x)° = 180°
12x = 180°
÷12 ÷12
x = 15
check your work
m<F + m<G = 180°
(4x)° + (8x)° = 180°
4(15)° + 8(15)° = 180°
60° + 120° = 180°
For anyone else who needs the right answer...it’s “parallel to the base”. I just did it and I got it right.
What do u need help on? It gives u the answer which is X=10/3
13/14 is already in simplest form because they have no common factors.
