Answer:
165
Step-by-step explanation:
Suppose fifth angle be x
x + 40° + 75° + 125° + 135° = 540° (sum of interior angles of a pentagon)
⇒ x + 375° = 540°
⇒ x = 540° – 375°
⇒ x = 165°

Answer:
The sum of the angles of a pentagon is = 540
Let the missing angle be - x
= x + 40 + 75 + 125 + 135 = 540
x + 375 = 540
= x = 540 - 375
x = 165
