Y= square root of x+ 15

y = 8 and x = 7

Step-by-step explanation:

I cant explain but here is what I did :

Squares are basically the consecutive sum of odd numbers i.e. if you add consecutive odd numbers , you will pretty surely obtain a square number . And since 15 cant be the sum of any two odd numbers , x and y had to be consecutive numbers . So , I did a bit of math and found out that the difference of squares of any two consecutive numbers is the sum of those two consecutive numbers i.e. if x and y are two consecutive numbers , x^2 - y^2 = x + y

I solved for x and y and I obtained the answer

25/4

step-by-step explanation:

call segment cd's length x. because dc and ab are parallel, angle acd and cab, so triangles adc and abc are similar and we can set up the equation x / ac = ac / ab, or x / 5 = 5 / 4 and x = 25/4.

hope this .
