Plz help and explain.

A

Step-by-step explanation:

We know that MN = MQ, which makes triangle MNQ an isosceles triangle. By definition, then, ∠MQR = ∠MNR and the height from the vertex of the triangle (point M) to the base (QN) is perpendicular and bisects ∠QMN. In other words, ∠QMR = ∠NMR = 36°.

Now, since QMR is a triangle, all three angles add up to 180, so we can find the angle MQR:

∠MQR = 180 - 36 - 90 = 54°

Now, since PQ = NO, we can say that PQNO is an isosceles trapezoid, so by definition, ∠PQN = ∠ONQ. And, since ∠MQR = ∠MNR = 54° and ∠MNO = 125, we can find ∠PQN = ∠ONQ:

∠PQN = ∠ONQ = 125 - 54 = 71°

Since PQRS is a quadrilateral, by definition, all angles will add up to 360. So, we have:

∠PQR + ∠QRS + ∠RSP + ∠SPQ = 360

71 + 90 + 90 + ∠SPQ = 360

∠SPQ = 109

Since ∠SPQ is the same angle as ∠OPQ, the answer is A.

the answer would be 150 books

step-by-step explanation:

if you divide 300 by 2 you will get 150

35 is an outlier
