Angle 10 is 140 degrees

Angle 2 = Angle 10 = 140 degrees (Vertically Opposite Angles)

Angle 5 + Angle 4 = Angle 2 (Corresponding Angles)
Angle 5 + Angle 4 = 140
90 + Angle 4 = 140 (Angle 5 is 90 degrees because c is perpendicular to d)
Angle 4 = 50

Agata [3.3K]

Answer:

<em>The sale price of a ticket from Orlando to Atlanta for someone under the age of 16 is </em><em>$29.5</em>

Step-by-step explanation:

The price of a train ticket from Orlando to Atlanta is normally $118.00.

i.e the normal sell price of a ticket is $118

But, the train company is offering a special 75% discount to children under the age of 16.

i.e the sell price of ticket for children is 75% less than the normal sell price.

So, the sell price is,

=118-\left(118\times \dfrac{75}{100}\right)\\\\=118-88.5\\\\=\$29.5

Therefore, the sale price of a ticket from Orlando to Atlanta for someone under the age of 16 is $29.5
