Question

two angles of a triangle are 30degree and 80degree. find the third angle.

Answer 1

let angle A = 30° and angle B = 80°
angle C = ?

Now Angle A + B + C = 180° (Angle sum property of triangle )

so 30 + 80 + C = 180°

C = 180 - 110
= 70°

Thus third angle = 70°

Hope it might be helpful

Answer 2

angle a = 30degree, angle b =80 degree ,angle c =?
angle a+angle b+angle c=180 degree
30+80+angle c =180degree
110+angle c=180degree
angle c=180-110
angle c =70degree
Hope its helpful to you.
