Answer:
56°
Explanation:
Sum of angles in a triangle= 180°
First Triangle= 56°
Second Triangle= 68°
Third Triangle= a
Ttherefore,
Sum of angles in a triangle= 56+68+a
180 = 56+68+a
180 = 124 + a
a = 180-124
a = 56°
Since 'a' was the third angle
Hence, The measure of the third triangle is 56°
The triangle now has <56°, <56°<, <68°.
