Well, the Pythagorean theorem is helpful.
Does 7^2+19^2=25^2?
no it desn't, so no it is not a right triangle
1.4 repeating?

Answer:
Step-by-step explanation:
Distance of (-3,4) to origin = √((-3)^2+4^2) = 5
sinθ = 4/5
cosθ = -3/5
tanθ = 4/(-3) = -4/3
cscθ = 1/sinθ = 5/4
secθ = 1/cosθ = -5/3
cotθ = 1/tanθ = -3/4
