Determine the area of a triangle with A=27.8 B = 107.3 c=4

B) 10 units^2

Correct question:

Determine the area of a triangle with A=27.8° B = 107.3° c=4

Area of the triangle is 5.04 units²

Step-by-step explanation:

Given;

A = 27.8°

B = 107.3°

C = 180 - (27.8 + 107.3) = 44.9°

c = 4

Now, we determine the remaining two sides of the triangle using sine rule

Apply Hero's formula;

Therefore, area of the triangle is 5.04 units²
