Question 22 of 25
Xelga [282]

Answer:

<h3>Option D</h3>

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°

Population of a town is 30,000 represents increase of 40% from five years ago. find the population
erma4kov [3.2K]
Well 50% of 30,000 is 15,000
So 10% is 3,000
15,000 - 3,000 = 12,000

So 40% increase is 42,000
