Answer:
- 7.71 km²
Step-by-step explanation:
<u>Area of triangle:</u>
- A = 1/2bh
We have the value of b but not h.
Added auxiliary segments which help to find the value of h.
<em>See attached for details</em>
- sin 40° = h/4
- h = 4 sin 40°
- h = 2.57 km
<u>The area is:</u>
- A = 1/2*6*2.57 = 7.71 km²
