Answer:
The required biconditional statement is: If Smith is guilty, if and only if Jones is innocent.
Step-by-step explanation:
From the provided statement.
The statement is: If Smith is guilty, then Jones is innocent.
The converse is: If Jones is innocent, then Smith is guilty.
The combination of a conditional statement and its converse is called biconditional statement.
The biconditional statement contains if and only if phrase between two part of the statement.
Which means the statement and converse both are true.
Therefore, the required biconditional statement is: If Smith is guilty, if and only if Jones is innocent.
The trigonometric function that can be used to find the value of x is 12 / tan ( 25 ) . The correct values of a and b will be 12 and 25 resp . .
Given :
A right angle triangle , one angle = 25 ° and side opposite given angle = 12 units .
Trigonometric Formula for Tan θ
tan θ = perpendicular / base , tan θ = ( sin θ / cos θ ) , tan θ = ( 1 / cot θ ) .
where θ = 25 , perpendicular = 12 , base = x .
Substituting values in above first formula ,
tan 25 = 12 / x
Therefore , x = 12 / tan ( 25 ) .
Hence , a = 12 and b = 25 .
