Two ropes, AD and BD, are tied to a peg on the ground at point D. The other ends of the ropes are tied to points A and B on a flagpole, as shown below:
Two ropes, AD and BD, are tied to a peg on the ground at point D. The other ends of the ropes are tied to points A and B on a flagpole. Angle ADC measures 60 degrees and angle BDC measures 30 degrees. The length of DC is 5 multiplied by square root of 3.
Angle ADC measures 60° and angle BDC measures 30°. What is the distance between the points A and B on the flagpole?

Best ResponseYou've already chosen the best response.0so find the length AC using the tan ratio and an angle of 60 then find BC, again using the tan ratio and an angle of 30 the the distance AB is AC  BC hope it helps

Best ResponseYou've already chosen the best response.0here is the start\[\tan(60) = \frac{AC}{5 \sqrt{3}}~~~then~~~AC = 5 \sqrt{3} \times \tan(60)\] and \[\tan(30) = \frac{BC}{5\sqrt{3}}~~~~~then~~~~BC = 5\sqrt{3} \times \tan(30)\] hope it helps
