Answer:
a.30.4 units²
Step-by-step explanation:
Using the triangle attached, we can find the angle at C which is 180-(22+105)=53°
Then we use the sine rule to find the value of side c.
14/sin105=c/sin53
c=(14/sin105)× sin53
c=11.575
We can now use the sine formula to find the area of the triangle. A=(1/2)absin∅
A= (1/2)×14×11.575sin22
A=30.4
