Answer:
(1) is 52°
(2) is 60°
Step-by-step explanation:
If you add (1) and 128°, you get a straight line which is 180°
so...
(1) = 180° - 128°
= 52°
Next...
since you have to find (2) and you already have the value of (1). The inner angles of the triangle makes 180°.
so..
or, (1) + (2) +68 = 180
or, 52° + 68° + (2) = 180°
or, 120°+ (2) = 180°
Therefore, (2) = 180° - 120°
= 60°
