Question

if a=40 degree,b=70 degree find the other angle?

Answer 1

if in a triangle it would be 40+70+x =180°
therefore third angle would be 180-110= 70°

Answer 2

Given,

a = 40°

b = 70°

let the other angle be x.

By angle sum property of a triangle,

==> a + b + x = 180°

==> 40° + 70° + x = 180°

==> x = 180° - 110°

==> x = 70°
