PLZ HURRY. find angle b I NEED HELP FIGURING OUT HOW TO DO THESE ROBLEMS IN GENERAL

b=42°

Step-by-step explanation:

This angle is an example of a complementary angle. This means that the total sum of its angle is 90°.

To work out the value of b you would simply minus the angle of 48 from the total of 90, this gives you 42°. This is because as the total is 90 and the value given is 48 and so to isolate the value of b you would minus the value given from the total.

1) Minus 48 from 90.

2) B=42°

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet
