2 adjacent angles of a parallelogram are (2x+45°) and (4x-15°) . What is the value of x?
2 answers:
Value of x is 25°
Step-by-step explanation:
- Step 1: Adjacent angles of a parallelogram are supplementary. Therefore their sum is equal to 180°
⇒ (2x + 45°) + (4x - 15°) = 180°
⇒ 6x + 30° = 180°
⇒ 6x = 150°
⇒ x = 25°
Step-by-step explanation:
