Nesesito ayuda con este problema ​

Hi sorry i don’t speak spanish :(

x=5
y=52

since AB and BC are the same length, you know it is an isosceles triangle
so two of the angles are the same
angle A and angle C are the same
so y = 52
A = C :. y = 52

all angles of a triangle add to 180
so add 52 and 52 to get 104
subtract 104 from 180 to get 76
set 14x + 6 = 76
14x = 70
x = 5

Im not that good with division but i think 5 is -6but dont quote me on thatim not the best in division but thats my answer
