False

Step-by-step explanation:

I believe if we're thinking in terms of an image for an actual plane, there would be no part of that plane in which if we placed in a cube, would result in a full circle. If we had the front of the plane enter the cube, it would still be at most a half circle, or half oval for that matter.

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,

what
