Wo boats start their journey from the same point a and travel along directions ac and ad, as shown below: abc is a right triangle with measure of angle abc equal to 90 degrees and length of ab equal to 100 feet. there is a point c on bd such that measure of angle acb is 60 degrees and measure of angle adc is 30 degrees. what is the distance, cd, between the boats? 284.3 ft 115.5 ft 230.9 ft 173.2 ft

115.5 feet

Step-by-step explanation:

See the diagram attached with the answer.

It is clear from the diagram

⇒ feet. {Since }

Again from the diagram

⇒ feet {Since }

Therefore, CD = BD - BC = 173.2 - 57.735 = 115.47 ≈ 115.5 ft. (Answer)

step-by-step explanation:

two pairs of adjacent sides are of equal length. this implies that one diagonal divides the kite into congruent triangles, and so the angles between the two pairs of equal sides are equal in measure. it also implies that the diagonals are perpendicular.
