Answer:
130
Step-by-step explanation:
You have to make this question into an equation. So let the equation be x+8=138. Then you subtract 8 from both sides. Bring down the x and you'll get your answer.
The sum of these two angles is 180°, therefore,
138° + (x + 8)° = 180°.
Simplify the left side of the equation.
146° + x = 180°.
Subtract 146 from both sides.
x = 34°
the answer should be the second one

for any pentagon the interior angles add up to n-2 times 180 degrees.
