4.

Once is opposite to , they are the same. It is the same for , equals to 40º.

m∠y = 40º

The ∠x and 40º are supplementary, therefore ∠x = 140º.

∠z = 140º

m∠x = 140º

m∠y = 40º

m∠z = 140º

5.

Considering the explanation from the question 4:

m∠x = 50º

m∠y = 130º

m∠z = 50º

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.
