Question

Conserve the following statements:
A: Angle between 2 ı with not stretchy bar on top minus m ȷ with not stretchy bar on top plus 3 m k with not stretchy bar on top text  and  end text left parenthesis 1 plus m right parenthesis ı with not stretchy bar on top minus 2 m ȷ with not stretchy bar on top plus k with not stretchy bar on top text  is acute  end text not stretchy rightwards double arrow m not an element of open square brackets negative 2 comma negative 1 half close square brackets
text  R: If  end text left parenthesis a with not stretchy bar on top comma b with not stretchy bar on top right parenthesis text  is acute then  end text a with not stretchy bar on top times b with not stretchy bar on top greater than 0 text  If  end text left parenthesis a with not stretchy bar on top comma b with not stretchy bar on top right parenthesis text  is obtuse then  end text a with not stretchy bar on top times b with not stretchy bar on top less than 0

  1. A is false, R is true
  2. A is true, R is false
  3. A is false, R is false
  4. A is true,R is true,R rightwards double arrow A

The correct answer is: A is true,R is true,R rightwards double arrow A
