I think it’s been awhile but just ur 140/360 then times that by pi then 2 then times r= 12.22
Answer:
-1.5
Step-by-step explanation:
The slope of a line is given by the formula:

Let's let (4,5) be x₁ and y₁ and let's let (8,-1) be x₂ and y₂. So:

Subtract:

Reduce:

So, our slope is -3/2 or -1.5.
And we're done!
K is the middle letter of the triangle JKL so it would be the same as the middle letter of the triangle EFG
so K = F
F = 62 degrees, so K = 62 degrees
