Answer:
21.53 m
Step-by-step explanation:
We can obtain the angle C;
C + 104.3 + 31.3 = 180 ( sin of angles in a triangle)
C = 180 - (104.3 + 31.3)
C = 44.4°
Using Sine rule :
c / sinC = a / sin A
Cross multiply :
c * sin44.4 = 29 * sin 31.3
c * sin44.4 = 15.066054
c = 15.066054 / sin 44.4
c = 15.066054 / 0.6996633
c = 21.533291
c = 21.53 m
