The sign shows the hours for an art museum a. Write a conditional to describe the hours of the museum on Mondays
b. Write a conditional to describe the hours of the museum on Thursdays
c. Write the converse, inverse, and contrapositive of the conditional in part (b). Then give the truth value for each statement
d. Can each conditional in parts (a) and (b) be written as a true biconditional? Why or why not? If so, give each biconditional

Answer: d. 39 cmin the diagram, the approximate length of the minor arc de is 39 centimetres.step-by-step explanation: the formula for the length of an arc in a circle is as displayed below.let the length of the minor arc de = xx = 2( pi )r × angle of sector / 360°from this, we will substitute the values given from the problem into the formula to obtain the length of the minor arc de.x = 2( pi )r × angle of sector / 360°r = radius = 25cmpi as an approximate value = 3.14angle of sector = 120°x = 2( 3.14 )( 25 ) × 120° / 360°x = 157 × 1 / 4x = 39.25x = 39 ( rounded to the nearest whole number as an approximate value )
