What is the sum of the measures of the interior angles formed by the boundary of this team pennant?
a) 360 degrees
b) 120 degrees
c) 180 degrees
d) 100 degrees

180°

Step-by-step explanation:

The sum of the measures of the interior angles formed by the boundary of this team pennant.

The shape of pennant is similar to triangle. It means pennant has 3 sides and 3 angle.

It would be triangle. As we know, the sum of measure of interior angles of a triangle is 180°

∠1 + ∠2 + ∠3 = 180°

Hence, The sum of measure of angles formed by boundary of pennant is 180°

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
