Triangle B C D is shown. Angle C D B is a right angle. Altitude a is drawn from point D to point E on side C B, forming a right angle. B D is labeled c and C D is labeled D. The length of B E is 18 and the length of E C is 4. What is the value of a? 6 StartRoot 2 EndRoot 9 8 StartRoot 3 EndRoot 36 StartRoot 2 EndRoot

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
