In the figure shown, the measure of angle PRS is how many degrees greater than the measure of angle PQR.

(1) The measure of angle QPR is 30°.
(2) The sum of the measures of angles PQR and PRQ is 150°.

Tough one.. Statements 1 and 2 essentially give same information, so you can go straight to D or E. I got 30 degreees difference, hence D.

30+(180-y)+z=180

y-z=30

1) the measure of angle qpr is 30
2) the sum of the measures of angles pqr and prq is 150

1) if qpr is 30, then prs is 90-x and pqr is 60-x, prs is 30 degrees > than pqr -> suff.

2) this yields the same that qpr is 30 degrees so it is suff. as well

Angle prs is equal to sum of opposite interior angles pqr and qpr. So, prs-pqr= qpr.

So, 1 is sufficient since qpr =30.

And pqr+prq = 150, So, qpr = 180 - (pqr+prq) = 180-150 = 30. So, 2 is also sufficient.

In the figure shown, the measure of angle PRS is how many degrees greater than the measure of angle PQR.

Q: <PRS-<PQR=?

(1) The measure of angle QPR is 30°. <QPR=30 --> in triangle QPR three angles sum=180=<QPR+<PQR+<PRQ -->180=30+<PQR+(180-<PRS) --> 30=<PRS-<PQR SUFFICIENT

(2) The sum of the measures of angles PQR and PRQ is 150°. Basically the same information is given <PQR+<PRQ=150 --> <PQR+180-<PRS=150 --> 30=<PRS-<PQR SUFFICIENT
