Two angles are supplementary .One angle has a mesure 2 times the other angles. What are the measures of each angles

90 degrees each

Step-by-step explanation:

Let's go!

One angle has a mesure 2 times the other angle

that is x+y=180

where y=2x

x+2x=180

3x=180

x=180/3

x=90.

x+y=180

90+90=180

As required

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

e^-kt = n/n0 = 0.79  

-kt = ln 0.79  

t = - ln 0.79/0.0001  

= 2357 years
