Answer:
Step-by-step explanation:
A
Answer:
{x,y} = {1,1}
Step-by-step explanation:
[2] 6y = -14x + 20
[2] y = -7x/3 + 10/3
// Plug this in for variable y in equation [1]
[1] -10x - 6•(-7x/3+10/3) = -16
[1] 4x = 4
// Solve equation [1] for the variable x
[1] 4x = 4
[1] x = 1
// By now we know this much :
x = 1
y = -7x/3+10/3
// Use the x value to solve for y
y = -(7/3)(1)+10/3 = 1
Solution :
{x,y} = {1,1}
I think that the best answer here would be that A = 40 degrees.
