Answer:
θ = π n - 20 for n element Z
Step-by-step explanation:
Solve for θ:
sin(θ + 20) = 0
Take the inverse sine of both sides:
θ + 20 = π n for n element Z
Subtract 20 from both sides:
Answer: θ = π n - 20 for n element Z
Step-by-step explanation:
if the vertex A is (-2;5), vertex B is (1;3) and the vertex C is (-1;0), then
1) the lengths are (note, the side AC should be hypotenuse):
2) if to check the equation AB²+BC²=AC², then
13+13=26 - it is true.
It means, the triangle ΔABC is right triangle.
