Vertical angles are where the top equals the bottom or the left equals the right angle. So we would do:
8x - 13 = 5x + 8
And then substitute.
3x = 21
x = 7

The length of a rectangular is 7/10 ft .and the width is 1/5ft what is the perimeter

Blababa [14]

<h3>Answer:</h3>

$\huge\boxed{1 \frac{4}{5}\ \text{ft}}$

<h3>Explanation:</h3>

Change $\frac{1}{5}$ so that is has a common denominator. $\frac{1*2}{5*2}=\frac{2}{10}$

Make an equation. $\frac{7+7+2+2}{10}$

Add. $\frac{14+4}{10}$

Add. $\frac{18}{10}$

Divide both sides by 2. $\frac{9}{5}$

Convert to a mixed number. $1 \frac{4}{5}$
