Question

Two angels of a triangle are 30°and 70°, find the angels of the triangles​

Answer 1

according to angle sum property of triangle sum of all angles is 180°

30°+70°+x=180°

100°+x=180°

x=180°-100°

x=80°

therefore the angles are 30°,70° and 80°

Answer 2

$sum \: of \: the \: interior \: \\ \\ angles \: of \: triangle \: is \: {180}^{0} \\ \\ {30}^{0} + {70}^{0} + {x}^{0} = {180}^{0} \\ \\ {100}^{0} + {x}^{0} = {180}^{0} \\ \\ {x}^{0} = {80}^{0} \\ \\ \\ mark \: me \: as \: brainliest$
