If triangle rst is an acute triangle, then m∠s must be

less than 90°.
equal to 90°.
equal to 100°.
greater than 90° and less than 180°.

m ∠ S must be less than 90°

Therefore; if triangle RST is an acute triangle; then;

∠R , ∠S and ∠T, all are less than 90.

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

multiple all that
