3. find the required information and justify your answers. for problems a-d use the parallelogram
at right.
a. find the perimeter.
b. if ct = 9, find at.
c. if mzcda = 609, find m cba and mzbad.
d. if dt= 4x – 7 and bt = -x + 13, solve for x.

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.

part a: 1.08

part b: 27.59
