Answer:
61%
Step-by-step explanation:
To solve this you have to find the change in the town's population.
Percentage wise we simply divide 25,800 by 42,600.

Now we round.
0.6056 The six rounds the 5 up, which will then round the 0 up.
Our change is 0.61.
Now to find the percentage we move the decimal point over two times to the right.
61% is the percentage of change.

Answer:
CAB = 70°
YZW = 120°
Step-by-step explanation:
CBA = 90° (right angle in a semicircle)
CAB = 180° - CBA - ACB ( angle in a triangle is 180°)
CAB = 180° - 90° - 20°
= 70°
YZW + YXW = 180° (opposite angle are supplementary in a cyclic quadrilateral)
YZW = 180° - YXW
= 180° - 60°
= 120°
