you follow me then I will give answer

Answer 2

Answer:

THIRD ANGLE = 70°

Step-by-step explanation:

first angle = 30°

second angle = 80°

let third angle = x°

we know that sum of angles of triangle is 180°

now,

30 + 80 + x = 180

 110 + x = 180

  x = 180 - 110

     x = 70

therefore, third angle = 70°
