Answer:
Option (D)
Step-by-step explanation:
In the picture attached,
An obtuse angle triangle ABC has been given.
By applying Sine rule in the triangle,
Since, m∠A + m∠B + m∠C = 180°
45° + 110° + m∠C = 180°
m∠C = 180°- 155° = 25°
b =
b = 15.56
b ≈ 15.56
a =
a = 11.712
a = 11.71
Therefore, Option (D) will be the answer.
