What is the measure of angle 1 and 2

(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°
