Answer:

x = 12; y = 12

B

Explanation:

TRiangles CED and BCA are similar by AA

<CBA = <CDE                 Marked as equal

<C is common to both triangles.

=============

y/24 are the two sides opposite <C This ratio is equal to

24/48 These two are opposite the angles marked in orange.

y/24 = 24/48               You could cancel the right side before cross multiplication

y / 24 = 1/2                   Cross multiply

2y = 24                         Divide by 2

2y/2 = 24/2                  Do the division

y = 12

======================================

Now use <CED and <A to get the ratio associated with their sides. These two angles are equal because the other two angles are.

18/(24+x)

Now use the two 2 orange angles

24/ 48 = 18 / (24 + x) and again cancel the left before cross multiplying.

1/2 = 18/(24 + x )             Cross multiply

24 + x = 2*18                  Do the multiplication  

24 + x + 36                     Subtract 24 from both sides.

24-24 + x = 36 - 24       Combine

x = 12
