Tan 70 = opposite side /adjacent side

tan70 = height / 12 solve for height

Because this is a right triangle, the angels are 90, 70, and 20. Use Law of Sines to figure out the pole: https://www.mathsisfun.com/algebra/trig-sine-law.html

(create a proportion with 70 degrees, 20 degrees, 12 and x for the missing side)
