Answer:

12.5%

Step-by-step explanation:

A population of a city went from 240,000 to 210,000, what is the percentage of decrease.

First step is to calculate the amount of the decrease of the population.

It went from 240,00 to 210,000, so it's a drop of 30,000, right?

To determine the percentage of decrease, we need to see how much that 30,000 weights compared to the original figure of 240,000:

30,000 / 240,000 = 1/8 or 12.5%

Answer:

AD= 8

DC= 15

Angle a= 112°

Angle b= 68°

Angle c= 112°

Step-by-step explanation:

We have to assume the figure is a parallelogram.

Opposite sides of a parallelogram are congruent, so ...

BC = AD = 8

AB = DC = 15

Opposite angles are congruent, and adjacent angles are supplementary.

180° - ∠D = Angle a = Angle c = 112°

∠D = Angle b = 68°
