Answer:
a) 52.5 ft. b)40.1ft c)12.5ft d) 72.6
Step-by-step explanation:
a) The height of the lighthouse is 84ft, and the angle of elevation is 58 degrees.
tan58=84/x
find x by dividing 84 by tan58, and you get 52.5ft.
b) do the same thing, except 131 is in the base of the right triangle shape. That being said, do tan17=x/131.
multiply 131 by tan17, and you get x=40.1 feet.
c) This question wants you to find the length of the slide, (basically the hypotenuse).
given the angle to be 46, do sin46=9/x
since sin is opp/hyp
9/sin46= 12.5ft
d) Find the angle of elevation by using inverse tan given the base to be 5, and the height to be 16ft.
tan^-1=(16/5)=theta
x=72.6 hope this helps!

Answer:
<h3>
X = 2 , X = -3</h3>
Option C is the correct option.
Step-by-step explanation:
Discriminant = 
Given d = 15
When discriminant D > 0 --> roots are real and distinct. ( unequal )
So , 
option has real and distinct roots.
Hope this helps..
Best regards!!
The answer is 200 because you multiply 20x12 you get 200
