The vertical angles are equal to each other, that is, one of the one-sided corners will be 116°.

The sum of the one-sided angles is 180°, which means: 4x+116 = 180°

4x = 180-116 => 4x = 64°

x = 64/4 = 16°.

The sum of two adjacent angles is 180°. which means, that: 2x-3y = 180-64 = 116°

2x-3y = 116°

-2x+3y = -116

-32+3y = -116

3y = -116-(-32)

3y = -84

y = -84/3 => y = -28.

What was the total distance, in miles, Eil has biked when he finally reached the library?

MrMuchimi

Answer:

Distance covered by Eli is $5\frac{19}{20}$ miles.

Step-by-step explanation:

Eli biked the distance from his home initially = $1\frac{1}{10}$ miles

Then he remembered that he had left a book at home.

He came back home and traveled the distance = $1\frac{1}{10}$ miles

Then he reached the library by traveling the distance = $3\frac{3}{4}$ miles

Total distance covered by him = $1\frac{1}{10}+1\frac{1}{10}+3\frac{3}{4}$

= $1 + \frac{1}{10}+1+\frac{1}{10}+3+\frac{3}{4}$

= 5 + $\frac{1}{10}+\frac{1}{10}+\frac{3}{4}$

= $5+\frac{2}{20}+\frac{2}{20}+\frac{15}{20}$

= $5+\frac{19}{20}$

= $5\frac{19}{20}$ miles

Therefore, distance covered by Eli is $5\frac{19}{20}$ miles.
