ANSWER
D.
EXPLANATION
The standard equation of the hyperbola is
We multiply through by 36 to obtain:
We now expand to get,
Expand :
To get the general form, we equate everything to zero to get,
The correct choice is D.
The answer is A) 45°. This is because angles 1 and 5 are vertical angles. Vertical angles are congruent.

Answer:
7361.56 yards
Step-by-step explanation:
Height of the tower = 906 yards
Mauricio's height = 2 yards
Angle of elevation =
Let the distance between Mauricio and the base of the tower be represented by x.
The difference between the height of tower and Mauricio's height = 906 - 2
= 904 yards
So that applying the appropriate trigonometric function, we have;
Tan θ =
Tan =
0.1228 =
x =
= 7361.5635
x = 7361.56 yards
The distance between Mauricio and the base of the tower is 7361.56 yards.
