When the British system of units was first developed, what was the most common object used as a basis for measuring length?

A. Animals
B. The king's castle
C. The human body
D. Automobiles

about 168 miles

step-by-step explanation:

114 plus 113 times 2 and 114 times 3

place r′ so that qr′ is parallel to the tangent.

now we get that ∠r′py=∠pr′q, where y is on the tangent, on the opposite side of p from x.

also, because of the symmetry, ∠r′py=∠qpx.

finally, note that no matter where we place r, as long as it's on the correct arc, we have ∠prq=∠pr′q.

stringing all these equalities together, we end up with ∠prq=∠qpx.

this picture will show how its going to look like.
