Question

pls answer step by step ​

Answer 1

Answer:

correct answer is 47

Step-by-step explanation:

p parallel to the line R

therefor angle PBA=ANG BAS=78

in triangle x+90+(78-35)=180

x+90+43=180

x+133=180

x=180-133=47

Answer 2

Answer:

x =12°

Step-by-step explanation:

It is given that PQ || RS

angle PBA = angle BAO ( Alternate angle)

angle BAO = 78°

angle BOA = 90°

In triangle BOA

angle BAO + angle BOA + angle OAB = 180°

78°+90° + OAB = 180°

168° +OAB = 180°

OAB = 180°-168°

OAB = 12°

Hence your final answer value of x is 12°
