Question

Angle of triangle=56 and other is of 78 find the one angle left

Answer 1

the other angle is 180-(56+78)
=180-134
=46°

Answer 2

heya

we know that sum of all angles I'm triangle is 180 °

let's consider one angle left be X

56 + 78 + X = 180

134 +X = 180

X. = 180 - 134

X = 46

therefore other angle is 46
