Answer:

Let us make the last unknown interior angle be "b"

b+a+36=180

b=180-36-a

b=144-a

for the main triangle,

a+144-a+a-28=180

2a+116=180

2a=180-116

2a=64

a=32

so a=32

You want to make a rectangular banner that is 18ft. Long with a trim around the entire border of the banner . You have no more t

Answer:

6 ft

Step-by-step explanation:

Given that:

Length of rectangular banner = 18 ft

Total trim of banner available = 48 ft

To find:

Possible widths of the banner = ?

Solution:

Maximum trim available of the banner around the entire border of the banner = 48 ft

i.e. we are given the total perimeter of the rectangular banner.

Formula for perimeter of a rectangle is given as:

$Perimeter = 2 \times (Length + Width)$

Putting the values of perimeter and length to find the value of width.

$48 = 2 \times (18 + Width)\\\Rightarrow 48 =36+2 \times Width\\\Rightarrow 2 \times Width = 48-36\\\Rightarrow 2 \times Width = 12\\\Rightarrow \bold{Width = 6\ ft}$

So, width possible is <em>6ft.</em>
