Identify p and q.Then use the Law of Detachment and a truth table to determine if the argument isvalid or invalid.The Law of Detachment:|(p → q) ^ p|→ q, or(p → q) A q|→ p1. Given the following argument:a) If an angle measures less than 90°, then it is not obtuse.b) MLABC = 75°c) ZABC is not obtuse.Identify p and q:p:9:Build a truth table:Is the argument valid or invalid? Why?

Proposition : It is a declarative statement which is either true or false. Argument : It is a…
