Answer:
thanks.
Step-by-step explanation:
The reciprocal parent function would be, F(x)= 1/x
One hand (the hour hand) would have moved to the number 1, while the minute hand would have made a full rotation and be on the number 12.
From the identity,
sin^2(x)+cos^2(x)=1
then
cos(x)=sqrt(1-sin^2(x))
where sin(x) is given as 0.42.
Note that the above answer applies to 0<x<90 degrees
