Please help, thank you

∠ABD = 38°

Step-by-step explanation:

first find,

∠BDE = 180° - DEB° - DBE° ∠DEB is parallel to ∠DBE so both have 71° angle.

        = 180° - 71° - 71°

        = 38°

Step-by-step explanation:

ABD is the tangent chord angle, which is the half the measure of the intercepted arc:

On the other hand, the same arc BD is intercepted by the inscribed angle, which is the half of the intercepted arc measure:

Since m∠DEB = 71°, the angle ABD is of same size:

answer: -2+√x,-2-√x

i hope this , i don't know if you're looking for a pair or not.

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
