The answer is D
Because if you replace the variables just by testing them they give the answer as X=-3 and Y=3.
In which replacing:
3(-3)+5(3)=6
and with the other equation we've got:
4(-3)+2(3)=-6
so they comply with the required to be the correct answer, even though you can make a system of equation.
Answer:
452
Step-by-step explanation:
Have a Wonderful day
Sine = opposite / hypotenuse
cosine = adjacent / hypotenuse
So, in a right triangle which has the opposite side equal to the adjacent side, we will have the sin (theta) = cosine (theta)
This would be an isosceles right triangle which is also called a 45 45 90 triangle.
sine (45) = 0.70711 and the
cosine (45) = 0.70711
