Utility pole is 35 ft tall. the pole creates a 50 ft shadow. what is the angle of elevation of the sun? round your answer to the nearest degree. show your work.

  35°

Step-by-step explanation:

The mnemonic SOH CAH TOA reminds you of the relationship between trig functions and sides of a right triangle. The pole and its shadow form the legs of the right triangle with the side adjacent to the angle of elevation being the shadow. "TOA" tells you ...

  Tan = Opposite/Adjacent

  tan(elevation angle) = (pole height)/(shadow length)

  tan(elevation angle) = 35/50 = 0.7

The inverse tangent function, arctan( ) or tan⁻¹( ), is used to find the angle from the value of its tangent.

  elevation angle = arctan(0.7) ≈ 34.99° ≈ 35°

the expected value of the random variable : 0, 1 and 2

i would be happy to . most people on would also love to i'm sure. if you just want someone who has done algebra before and want a little more personal relationship than just begging strangers for , i can certainly be of service. i do have college myself so i might not be 24/7.
