Sagot :
Answer:
44°
Step-by-step explanation:
Given that :
Two angles are equal sized;
Let the angle = x
Third angle = 12 smaller than first, x - 12
The measure of the third angle ;
Sum of angles in a triangle = 180°
First + second + third angle = 180°
x + x + (x - 12) = 180
2x + x - 12 = 180
3x = 180 - 12
3x = 168°
x = 56°
The third angle :
(x - 12) = 56 - 12 = 44°
