Find the measure of the unknown angle for the following. 1. a triangle with angle measures of 66° and 77°

2. a right triangle with one angle measure of 36°

3. a quadrilateral with angle measures of 144°, 84°, and 48°

4. Divide a six-sided polygon into triangles to find the sum of its interior angles.​

1. 37°

2. 54°

3. 84°

Step-by-step explanation:

1. 180-(66+77)=37°

2. 180-(90+36)=54°

3. 360- (144+84+48)

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
