Find the measure of the arc or angle indicated. Assume that lines which appear tangent are tangent.

Step-by-step explanation:

Recall that the angle formed by two tangents is half the difference of the intercepted arc.

Multiply through by 2 to get:

26x+20=49x+10-180+13x+10

Group similar terms to get:

26x-13x-49x=10-180+10-20

-36x=-180

x=5

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
