Answer:

Lines are parallel if the sum of external angles of same side is 180°.

Step-by-step explanation:

Let one of the external angle is α°.

and other external angle is β° which is equal to α°/11. (∵ Given on is 11 times smaller than the other.)

Also β° = 1/6 of the right angle = (1/6)×90° = 15°.

β° = α°/11 , ⇒ α° = 11×β° = 11×15° = 165°.

α°+β° = 165° + 15° = 180°.

Here, sum of the two external angles = 180° ⇔ the given lines are parallel.

Three cities form a right triangle on a map. Cities B and C are the furthest apart. If cities A and B are 14 miles apart And cit

nekit [7.7K]

Answer:

26.1miles

Step-by-step explanation:

If three cities A, B and C form a right triangle on a map, and the Cities B and C are the furthest apart, then the distance between cities B and C will be the hypotenuse of the triangle.

If cities A and B are 14 miles apart, then |AB| = 14miles

Also if cities A and C are 22 miles apart, then |AC| = 22miles.

To get |BC| which is the distance between cities B and C, we will use the Pythagoras theorem.

|BC|² = |AB|² + |AC|²

|BC|² = 14²+22²

|BC|² = 196+484

|BC|² = 680

|BC| = √680

|BC| = 26.1miles

This means that cities B and C are 26.1miles apart

Jay is saving two-thirds of his savings account for his college education. If he has set aside $2500 from his savings for his co

Dvinal [7]

Answer:

$\dfrac{2}{3}x = \$ 2500$

$3750

Step-by-step explanation:

Given that:

Jay saves $\frac{2}{3}^{rd}$ of the savings account for his college education.

Money set aside for the college education = $2500

To find:

Total money present in the savings account of Jay = ?

Solution:

Let the total money in the savings account be $ $x$ .

As per question statement:

$\dfrac{2}{3}x = \$ 2500$

The equation to model the problem is:

$\dfrac{2}{3}x = \$ 2500$

Now, let us solve the above equation:

$\Rightarrow 2x =3\times 2500\\\Rightarrow x = \dfrac{7500}{2}\\\Rightarrow x = \bold{\$ 3750}$

Total money saved in the savings account is $3750.

Out of the total money $2500 is saved for college education.
