Final answer:
The question lacks sufficient information to determine the value of 'x'. Further details and context are needed to solve for 'x' in triangle ABC.
Step-by-step explanation:
The student's question does not provide complete information to solve for 'x'. The provided information seems to be a mixture of different problems. Specifically, the value for m∠ADB is given as an expression (3.2 + 15).
However, without an equation or further context, one cannot solve for 'x' with the information given. Also, portions of the text seem to be referring to unrelated problems, which do not contribute to solving for 'x' in triangle ABC.
To provide an accurate solution, additional information is required, such as a specific relationship between 'x', the angle m∠ADB, and other known sides or angles of the triangle.
The complete question is: In triangle ABC, where BD is an altitude and m∠ADB = (3.2 + 15), what is the value of 'x'? is:
