Answer:
45 degrees
Step-by-step explanation:
AOB = 140°
and an the angle bisector(OC) is a line which will divide AOB into 2 equal angles
which is 140÷2= 70
and if AOD = 25 then COD= 70-25
= 45 degrees

Answer:
B
Step-by-step explanation:
Using the Sine Rule in ΔABC
= =
∠C = 180° - (82 + 58)° = 180° - 140° = 40°
Completing values in the above formula gives
= =
We require a pair of ratios which contain b and 3 known quantities, that is
=
OR
= → B
