Answer:

∠BFC = 50

Step-by-step explanation:

∠AFC = 90

∠AFB + ∠BFC = 90

40 + ∠BFC = 90

∠BFC = 90 - 40

∠BFC = 50

Answer: B-C

Step-by-step explanation:

I believe it is the angle of B-C becuase B-E is a strieght line which equals 180. Also EFD looks the same as AFB so it is 40. And DFC is 90 becuase of the square. So we take 180-40-90=50. And the only one that is not solved is B-C

Answer:

(1,-3) and (-2,0)

Step-by-step explanation:

$x+y=-2$

$y=x^2-4$

Applying the second equation to the first

$x+x^2-4=-2\\\Rightarrow x+x^2-4+2=0\\\Rightarrow x^2+x-2=0$

Solving the equation we get

$x=\frac{-1+\sqrt{1^2-4\cdot \:1\left(-2\right)}}{2\cdot \:1}, \frac{-1-\sqrt{1^2-4\cdot \:1\left(-2\right)}}{2\cdot \:1}\\\Rightarrow x=1, -2$

When x = 1

$y=-2-1\\\Rightarrow y=-3$

When x = -2

$y=-2-(-2)\\\Rightarrow y=0$

So, the line and curve will intersect at points (1,-3) and (-2,0)
