AD is the perpendicular bisector of BC. BD = 5x – 10 and DC = 3x + 10.
Determine the value of x.

Which of the following would represent the sum of 3 consecutive integers if x is the first integer?

Find the length of cu, the triangles are similar.

In the given triangle, ∠aed ∼ ∠ abc, ad = 6.9, ae = 7.2, de = 5.2, and bc = 10.2. find the measure of bd and ce. round your answer to the nearest tenth.
