Answer:

66° by adding up 75° and 39°, we get 114°.

since all triangles equal 180°, 180° minus 114° is 66°

Answer:

66°

Step-by-step explanation:

For this type of question, first you should know that all the three angles of a triangle sum up to 180°. Let's say the three angles are ∠a, ∠b and ∠c, so if we add the values of all these three angles they would always be equal to 180°.

In this question, we are given the measure of two angles and are asked to find the third angle:

75° + 39° + ? = 180°

? = 180° - 75° + 39°

? = 66° Answer

Hope that helps...

Find the area of the triangle.

Len [333]

Answer:

123.948 km²

Step-by-step explanation:

We can use the equation: AΔ = 1/2*ab*sinθ, 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: AΔ = 1/2*22*24*sin(28°)

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

Simplify: 123.948 km²
