Angle ADC measures 60° and angle BDC measures 30°. What is the distance between the points A and B on the flagpole?

Answer 2

20

Answer 3

You have to 30-60-90 triangles. Using the ratio of the sides, find the measure of the whole side, AC
AC: 10√3 is the side oppostie the 30º, so the measure of the side opposite the 650 is 10√3*√3 = 30
Now, find the measure of the side BC.
BC = 10
Now subtract the two sides.
AC - BC = AB
30 - 10 = ?
