Which choice is equivalent to the expression below ?

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.

hope this by jack monhen

this would be 35. 35 + 5 = 40. you take the known constant and subtract by the answer of the equation and you get y.

1 a and 2 b

hope this

in the middle of nh?  

i think you need to show more to answer this question
