Rufina [12.5K]2 years ago
4 0

Answer:

Option (1)

Step-by-step explanation:

<em>For convenience sake, I will be omitting the arguments of the trig functions.</em>

3sin = sin - sqrt(3)

2sin = -sqrt(3)

sin = -sqrt(3)/2

So, the answer is 4pi/3 and 5pi/3.

Find the area of the triangle.
Len [333]

Answer:

123.948 km²

Step-by-step explanation:

We can use the equation: <em>AΔ = 1/2*ab*sinθ</em>, where a and b are the lengths of the sides next to the known angle, and θ is the angle itself.

Plugging in the numbers we know, we get: <em>AΔ = 1/2*22*24*sin(28°)</em>

Simplify: <em>AΔ = 264*.4695</em> (0.4695 is approximately sin(28°))

Simplify: 123.948 km²
