The angle BAC and DCA are alternate interior angles , Option D is the right answer.
What are Parallel Lines ?
The lines in a plane which never intersect and are at a same distance always are called Parallel Lines.
In the given question it is given that there are two lines FG and DE
The lines are parallel to each other , and transversal are AC and BC .
The angle BAC and DCA are alternate interior angles as AC is the transversal of the parallel lines.
Option D is the right answer.

Answer:
x ≈ 2879.4 m
Step-by-step explanation:
Measure of ∠DAC = 10°
Measure of ∠DAB = 90°
Measure of ∠BAC = 90° - 10° = 80°
By applying cosine rule in ΔABC,
cos(80°) = 
= 
0.17365 = 
x = 
x = 2879.36
x ≈ 2879.4 m
Answer:
1. (4,5)
The average rate of change of f(x) remain constant (4). Over the interval (4,5), g(x)=5,2 exceeding the change of f(x).
2. None!! REMAIN CONSTANT AND INCREASE.
The rate of change of f(x) remain constant (4) and g(x) increases.
3. g(x) exceeds the value of f(x)
F(X)=31 < G(X)=35,7
4. EVENTUALLY.
