Question

In ∆ABC, if ∠A= 48° , ∠B=56° then ∠C= ?​

Answer 1

We know that,

The sum of the three angles of any triangle is equal to 180°.

So, 58+48=106

180-106=74

58°+48°+74°=180°

So, ∠A= 48° ∠B= 48° ∠C=74°

Answer 2

<A=48°

<B=56°

Then,<A+<B+<C =180° (Sum of all angles of a triangle)

=48°+56°+<C=180°

=104°+<C=180°

=<C=180°-104°

=<C=76°

Hence,<C=76°
