unit 3: parallel and perpendicular lines homework 3: determined if ll m based on the line information given on the diagram. if yes, state the converse that proves the lines are parallel

  21.3

step-by-step explanation:

multiplying the given equation by c/sin(25°), we get

  c = 9/sin(25°) ≈ 21.2958 ≈ 21.3

we assume "c" is the length of ab, the side opposite angle c in triangle abc.

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.

its the second choice.

step-by-step explanation:

the elements in the range will be 7 less than the elements in the domain.
