Question

helpp plss!!!
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...Angle ADC measures 45° and angle BDC measures 30°. What is the distance between the points A and B on the flagpole?

Answer 1

We can find the measure of angle A

Answer 2

tan 30=bc/5sqrt.of3

Answer 3

Answer 5

@Yahoo!

Answer 6

Compute cos(30) = 5*sqrt(3) / DB and solve for DB

Answer 7

Calculate angle A by subtracting (30+45) + 90 from 180

Answer 8

wait but wats angle a ??? @RBauer4

Answer 9

tan 75=ab+bc/5sqrt of3

Answer 10

tan 30=bc/5sqrt.of3

Answer 11

i still dont get it:( @poohtooth @RBauer4

Answer 12

get bc first by bc= tan30/5sqrtof 3

Answer 13

A = 180 - (30+45) - 90
