Is the diagram, MN, PQ and RS are three intersecting straight lines. Which of the following statements is/are true? i. t = y ii. x + y + z + m = 180o iii. x + m + n = 180o iv. x + n = m + z
Attached Figure / Diagram
A
i and iv
B
ii
C
iii
D
iv
Verified Correct Answer: C.
Step-by-Step Mathematical Solution
m + y + x = 180o(sum of < s on straight line)
y = n(vertically opp. angle)
m + n + x = 180o
