Write the value of x

x=110

Step-by-step explanation:

Use the polygon formula (n-2) × 180 where n is the number of points

The polygon has 7 points

(7-2) * 180 = 5 * 180 = 900

All the angles should add up to 900

119+86+167+283+64+71+x=900

x=110

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.
