Answer 2

$\huge\bold{Given:-}$

One of the angles of a triangle is equal to the sum of other two. Find the measure of this aangle.

$\huge\bold{To\:Find:-}$

Find the measure of this angle.

$\huge\bold{Solution:-}$

Let the triangle be ΔABC and ∠B=∠A+∠C

But, sum of angles of triangle =180°

⇒∠A+∠B+∠C=180°

⇒∠B+∠B=180°

⇒∠B=90°
