width (b) =?

length(l)=3

perimeter (p)=?

now,

perimeter = 2(l+b)

or,72= 2(3+ b)

Answer : 110 degree

To find angle 1 , we apply outside angle theorem Lets name each point Measurement of arc EF=280 degrees

Measurement of arc GH = 60

Angle D = angle 1

Please refer to the theorem attached below

$angle D = \frac{arc(EF)-arc(GH)}{2}$

Now we plug in the values

$angle 1 = \frac{280-60}{2}$

angle 1 = 110

Measurement of angle 1 = 110 degrees

Answer:

Larger for the sample of Canadians

Step-by-step explanation:
