Answer 1

Answer:

EXERCISE 6.3

1. In Fig. 6.39, sides QP and RQ of A PQR are produced to points S and T respectively.

If Z SPR = 135º and Z POT = 110°, find Z PRO.

2. In Fig. 6.40.2 X=62º. 2 XYZ = 54°. If YO and ZO are the bisectors of ZXYZ and

ZXZY respectively of AXYZ, find Z OZY and Z YOZ.

3. In Fig. 6.41. if AB II DE, Z BAC=35º and Z CDE=53º. find ZDCE.
