tatiyna

Answer:

16. Yes

17. Yes

Step-by-step explanation:

Since the angles are congruent (due to parallel lines) the two triangles are similar. Similar triangles form congruent ratios between their corresponding sides.

Since the quadrilaterals are similar, this means the angles in each are congruent. This will not change when divided by diagonals. The triangles in each will have congruent angles and their sides will maintain equivalent ratios.

The bear can walk at a rate of 2 mph, which means after 4 hours it could have traveled 8 miles. That is our radius. To calculate the area of a circle, remember the formula
A = \pir^2

3.14 * 8^2 = A
3.14 * 64 = A
200.96 = A

An area of 200.96 square miles must be searched.
