Answer:

BC = 84

Step-by-step explanation:

Given

See attachment

Required

Find BC

The sum of angles\ at\ a\ point is 360.

So:

7n + 12 + 13n - 16 + 6n = 360

Collect like terms

7n + 13n + 6n = 360 + 16 - 12

26n = 364

Solve for n

n = 364/26

n = 14

From the circle:

BC = 6n

Substitute 14 for n

BC = 6*14

BC = 84

The length of a rectangle is three times its width. if the area of the rectangle is 300 yd2 , find its perimeter.
Svetradugi [14.3K]
Let, width = x
Length = 3x

It is given that, 3x * x = 300
3x² = 300
x² = 300 / 3
x = √100
x = 10
& 3x = 3(10) = 30

Perimeter = 2(l + w)
P = 2(10 + 30)
P = 2(40) = 80

In short, Your Answer would be 80 Yards

Hope this helps!
