What is the messure of N and the two angles; an-16 and 6n
AURORKA [14]

Answer:

14, 96,84

Step-by-step explanation:

8n  - 16 + 6n = 180 {Supplementary angles}

<u>8n + 6n</u>  -16 = 180

Combine like terms

14n - 16 = 180

Add 16 to both sides

14n = 180 + 16

14n = 196

Divide both sides by 14

n = 196/14

n = 14

8n - 16 = 8*14 - 16 = 112 - 16 = 96

6n = 6 *14 = 84

The length of a rectangle is 3ft less than double the width, and the area of the rectangle is 14ft^2 find the dimensions of rect
german

Answer: 4\times 3.5\ ft^2

Step-by-step explanation:

Given

area of the rectangle is A=14\ ft^2

Suppose width is given by w

So, length is l=2w-3

The area of a rectangle is A=l\times w

putting values

\Rightarrow A=(2w-3)w\\\Rightarrow 14=2w^2-3w\\\Rightarrow 2w^2-3w-14=0\\\Rightarrow 2w^2-7w+4w-14=0\\\Rightarrow w(2w-7)+2(2w-7)=0\\\Rightarrow (2w-7)(w+2)=0\\\\\Rightarrow w=\dfrac{7}{2}\ ft

length is l=4\ ft
