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

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.
