Question

Adjacent angles of parallelogram are y° and (2y - 36)°. Find the value of y.​

Answer 1

Answer:

y = 72°

Step-by-step explanation:

we know that  the sum of the adjacent angles of a parallelogram is 180 degrees.

therefore,

y + (2y  - 36) = 180°

y + 2y - 36 =180°

3y = 180 + 36

3y = 216

y = 216/3

y = 72°

Answer 2

☀ Given that: Adjacent angles of a parallelogram are  y° and (2y - 36)°

   Need to find: Value of y

Must know:

• When sum of two angles is 180°, they are called supplementary
• Adjacent angles of a parallelogram are supplementary

Solution:

→ y + ( 2y - 36 )° = 180°

→ y + 2y - 36° = 180°

→ 3y - 36° = 180°

→ 3y = 180° + 36°

→ 3y = 216°

→ y = 216/3

→ y = 72

_______________

• Henceforth, the value of 'y' is 72.
