Answer:
y = 2,305 homes
Step-by-step explanation:
2015-1995 = 20
84*20 = 1,680
1,680 + 625 = 2,305
Therefore, there were 2,305 homes in the town in 2015.
Option A:

Solution:
<u>To evaluate tan(105)°:</u>
105° can be written as sum of 60° and 45°.
tan(105)° = tan(45 + 60)°
Using the summation identity:


We know that, tan(45)° = 1 and tan(60)° = √3
Substitute this in the above equation.


To rationalize the denominator multiply by the conjugate
.

Using exponent formula:
and 

Using exponent formula: 





Hence option A is the correct answer.
