In ΔQED, m∠Q = 90 and m∠D is twelve degrees less than twice m∠E.
Find m∠E.

the distance between point a and point b is 6 units

if this is really you s much. i only have 3 points left and i have 2 questions to ask

step-by-step explanation:

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
