Answer:
9
Step-by-step explanation:
use the formula m = y2- y1 / x2 - x1
Answer:
Option (D)
Step-by-step explanation:
In the given triangle ABC,
Sum of all interior angles = 180°
m∠A + m∠B + m∠C = 180°
72° + 85° + m∠C = 180°
m∠C = 180 - 157
m∠C = 23°
By applying Sine rule in the triangle,




a =
= 15.09

b = 
b = 15.81
Therefore, option (D) will be the answer.
Step-by-step explanation:
