This problem refers to right triangle ABC with C = 90°. Begin the problem by drawing a picture of the triangle with both the given and asked for information labeled appropriately. If A = 39° and c = 86 cm, find b. (Round your answer to the nearest whole number.)

The answer is b = 55

Step-by-step explanation:

First off if you add every corner's degrees for the triangle together it should be equal to 180 degrees.

You would first do 39 + 86 = 125 and then subtract 125 from 180. 180 - 125 = 55.

There you have your answer!

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
