Answer:
42
Step-by-step explanation:
Hey There!
Angle 3 and Angle 4 are a pair of supplementary angles meaning that added together they will equal 180
So if angle 4 is given to find angle 3 all we have to do is subtract the angle that is given from 180
180-138=42
Therefore angle 3 = 42

Answer:
an = 4n +5
Step-by-step explanation:
First we need to find a common difference
d = a2-a1 = 13-9 = 4
The formula for an
an =a1+d(n-1)
an = 9 + 4(n-1)
Distributing
an = 9+4n-4
Combine like terms
an = 4n +5
