Answer» :THIRD angle = 60⁰Given :The measures of two angles of a triangular are 50⁰ and 70⁰To find :Measures of third angleSolution :Given that, two angles of triangle are 50 and 70Let the third angle be xAs we know that:sum of all angles of a triangle is 180⁰Now According to Question:➝ 50 + 70 + x = 180➝ 120 + x = 180➝ x = 180 - 120➝ x = 60 Hence Third angle is 60⁰ More Explanation :sum of all angles of a triangle is 180⁰∠A + ∠B + ∠CThe three angles in any triangle ALWAYS make a 180⁰ is iscoscles, right angle , EQUILATERAL, SCALENE triangles. |
