Step-by-step explanation:
sum of all side of angle of a triangle=180
angle A +angle B+ angleC=180
50+50+x=180
x=180-100
x=80°

X = 80°
We know that,
Some of all side of Δ = 180°
Then,
∠a + ∠b + ∠c = 180° ........(1)
Because,
∠a = 50°
∠b = 50° &,
∠c = x°
After Solving Eq(1) We get
∠a + ∠b + ∠c = 180°
50° + 50° + x° = 180°
100° + x° = 180°
x° = 180° - 100°
x° = 80
