Question 22 of 25

Answer 1

Answer:

Option D

The value of y in the parallelogram is 34°

Step-by-step explanation:

Adjacent angles of the Parallelogram are supplementary

So,

(78° + 3y°) = 180°

78° + 3y° = 180°

Subtract 78° each side we get,

78° - 78° + 3y° = 180° - 78°

3y° = 102°

Now, Divide both side by 3 we get,

3y°/3 = 102°/3

y = 34°

Thus, The value of y in the parallelogram is 34°
