If AC = 18 and CD = 5, AD = [?]

13

Step-by-step explanation:

ADC   if this line is AC=18

DC      and this is line CD=5

We can just substract 18-5 to get AD which is 13

x = 17

step-by-step explanation:

in the given figure, two triangles are inscribed in a circle where ∠bae ≅ ∠dae which makes the side be and de equal so we can write it as:

3x - 24 = x + 10

solving this equation for x to get:

3x - x = 10 + 24

2x = 34

x = 34/2

x = 17

therefore, the value of x = 17.
