If the slice is made parallel to the base, then if the base is a rectangle, the cross-section would be A. rectangle
Well the actual answer is 6x=6788. Na I’m just kidding juss needa stack up these points✨
Answer:
x = 6
Step-by-step explanation:
Looking at the attached figure:
As the triangle ABC is inscribed inside the circle and AB is the diameter of the circle => ABC is the right triangle
So that ∡ACB = 90°
As ACB is the right triangle, according to the Pythagoras theorem, we have the formula as following:
=> 
=> BC = 12
As O is the center of the circle
=> OA = 1/2 x AB = 1/2 x 20 = 10
Inside the triangle ABC, as OD is parallel with BC
=> AOD and ABC are similar triangles
=> 
=> 
=> x = 1/2 x 12 = 6
So x = 6
I think the answer is 2. If I calculated right. Hope I helped.
