Find the value of t in the diagram
Attached Figure / Diagram
A
63\(^o\)
B
117\(^o\)
C
126\(^o\)
D
234\(^o\)
Verified Correct Answer: C.
Step-by-Step Mathematical Solution
In the diagram,
\(\alpha\) = 180\(^o\) - 177\(^o\) (angles on a straight line)
\(\alpha\) = 63\(^o\)
t = 2 x 63\(^o\) (angle at centre = 2 x angle at circum)
= 126\(^o\)
