Answer:

81 is the perfect square of the first option

Step-by-step explanation:

It is asking for the perfect square so the third option will be eliminated because that is cubed.

The fourth option will also be eliminated because it is multiplication.

The second option will be eliminated because it has addition.

81 is the perfect square of the first option

How to solve this using trigonometry?
Leya [2.2K]
Using SOHCAHTOA and Kenui's height and angle of depression (which is the downward angle from the horizontal ) the answer should be:  

because its the Adjacent and Opposite sides use Tan;  
Tan(6.8) = o/a
tan(6.8) = Distance / 219
tan(6.8)(219 = Distance 
26.114 m 

But because the angle of depression is the downward angle from the horizontal the answer may be Tan(83.2)(219) = 1836.589
the 83.2 coming from 90 degrees - 6.8 degrees 

either way i"m still unsure because I don't see a need for the two angles or Mias involvement, sorry if I'm wrong
