The answer is 11.2 which means 11 1/5
<u>Answer-</u>
<em>The values of </em><em>x and y are 20° and 30</em><em>, respectively.</em>
<u>Solution-</u>
As in the given triangle all the angles are same so it must a equilateral triangle.
In an equilateral triangle all the measurements of the angles and side length are same. The measurement of the angels are 60°.
As given in the question one side length is 46, so all the side length are same.
So,

We know that an exterior angle of a triangle is equal to the sum of the opposite interior angles. 80° is the exterior angle opposite to x and one angle of triangle at the top vertex.



Therefore, the values of x and y are 20° and 30, respectively.
Each small doll cost 6.5 dollars and each large doll cost 10 dollars
It would seem that the 25% down and 25% increase would cancel each other out and the shoes would remain $60
