Answer:
Bro i dont know if i am right but here we go
The answer most likely is 80
Step-by-step explanation:
By useing a bit of geometry instead of useing two angles to find your last angle.
So first notice how there are two of the same sides (14)but one differnt side(18) okay nice
With that info it is clear that it is a isosoles triangle (triangle with two equal sides and angles) so from that information two of the angles are gonna be the same. Luckely you were given an angle.
So that means there are two 50 angels and an X angle and to solve for X angle you need to add 50 + 50 = 100 then subtract to 180 then boom 80
I hope you understand and im sorry if this is wrong.
