Does anyone know how to solve this problem?

Answer:
50, 130
Step-by-step explanation:
Since they are a linear pair they add to 180
z + ( 2.4z+10) = 180
Combine like terms
3.4z + 10 = 180
Subtract 10 from each side
3.4z+10-10 = 180-10
3.4z = 170
Divide each side by 3.4
3.4z/3.4 = 170/3.4
z = 50
2.4z + 10 = 130
