Question

pls answer these 3 question​

Answer 1

Answer:

1 . 30 degree

Explanation:

AB parallel PQ

angle ABQ + angle PQB = 180 .....(Interior angles )

60 + x = 180

x = 120

angle PQB = angle RQS .....(vertically opposite angles )

angle RQS = 120

Sum of measure of all angles of triangle is 180

angle RSQ = 180 - angle RQS - QRS

= 180 - 120 - 30

= 30

2. in fig

ABC = 66 & BCD = 30 +36 =66

ABC = BCD

alternate angle test

AB parallel CD

angle CEF + ECD = 150 + 30 = 180

Interior angle test

CD parallel EF

AB parallel CD parallel EF

AB parallel EF

follow me first then I will give third answer
