Question

please give me the answer with steps... please please​

Answer 1

Answer:

PQR = 60

QRP = 70

RPQ = 50

DPR = 70

Answer 2

Step-by-step explanation:

Here CD is parallel to AB.

=>alternate interior angles are equal and interior angles on same side of transversal are supplementary.

(a) =>angle(CPQ) = angle(PQR) = 60°

(b) angle(QRP) + angle(PRB) = 180° (linear pair)

=>angle(QRP) = 180 - 110 = 70°

(c) angle(RPQ) + angle(QRP) + angle(PQR) = 180° (sum of interior angles of triangle is 180)

=>angle(RPQ) + 60 + 70 = 180

=>angle(RPQ) = 180 - 60 - 70 = 50°

(d) angle(DPR) + angle(PRB) = 180°

(interior angles on same side of transversal)

=> angle(DPR) = 180 - 110

=> angle(DPR) = 70°
