Answer:
A.) About 90
Step-by-step explanation:
From the given table, the biologist tagged 150 trout. Also, he recaptured a total of 100 trouts of which 60 were recaptured with tags.
Thus, let the trout population in the lake be represented by x,
= 
Cross multiply to have;
100 × x = 60 × 150
100x = 9000
Divide both sides by 100,
x = 
= 90
Therefore, the trout population is about 90 in the lake.

Answer:
None
Step-by-step explanation:
By graphing out the both line segments through graphing software, segments AB and CD have no intersections on the co-ordinate plane.
I've attached a screenshot of what i graphed out.

Answer: 23</h3>
The three angles of any triangle always add to 180, so,
z+62+95 = 180
z+157 = 180
z+157-157 = 180-157 .... subtract 157 from both sides
z = 23
As a check,
z+62+95 = 23+62+95 = 180
so the answer is confirmed.
