A man is seeing a tower at an angle of 84.6 degrees and standing at a distance of 100 ft from the base of the tower .find the height of tower?

Angle of inclination,x = 84.6 degree distance of man from tower base,y = 100ft now we use trigonometric ratio tanx to calculate height of tower tanx = opposite side/adjacent side from given question, tan 84.6 = height of tower,h/distance of man fro tower base,y tan 84.6= h/y h=y X tan84.6 = 1058 ft so height of tree is approx. equals to 1058 ft
