plss mark me brainlist

Answer 2

Answer:

If AB parallel to CD

and PS Is a transversal then,

7x+14=angle QRD(alternate interior angles)

also

angle QRD+4x+89=180°(adjacent angles)

If angle QRD=7x+14

then we can use 7x+14 in the equation of QRD+4x+89

therefore

7x+14+4x+89=180(

11x+103=180

11x=180-103=77

x=77/11=7

therefore the angles are

7x+14=7×7+14=49+14=63°

angle QRD=7x+14=63°

4x+89=4×7+89=117°

also

117+63=180°

180=180

L.H.S=R.H.S

hence verified

hope it helps
