Question

an exterior angle of a triangle is 140 degree and one of its interior angles is of measure 45 degree find the measure of the Other interior opposite angle​

Answer 1

$\large{\mathcal{\blue{Answer}}}$

➡using theorem:An exterior angle of a triangle is equal to the sum of the interior angles.

let the other interior angle be X

$\large{140=X+45}$

$\large{140-45=X}$

$\large{\mathcal{\blue{X=95degree}}}$

Answer 2

$\large \bold{ \underline{ \underline{ \: \: Answer : \: \: \: }}}$

$\to$ The other interior angle 95°

$\large \bold{ \underline{ \underline{ \: \: Explaination : \: \: \: }}}$

$\huge{ \star{}}$ An exterior angle of a triangle is equal to the sum of the interior angles

Let , the other interior angle be x

$\to{140=x+45} \\ \\ </p><p> \to {x = 140-45} \\ \\ </p><p> \to {x = 95 ° }$

Hence , the other interior angle is 95°
