Answer:
k=4
Step-by-step explanation:
5-7k=-4(k+1)-3
Distribute
5-7k=-4k-4-3
Combine like terms
5-7k=-4k-7
Add 7k to each side
5-7k +7k = -4k+7k-7
5 = 3k-7
Add 7 to each side
5+7 = 3k-7+7
12 = 3k
Divide by 3
12/3 = 3k/3
4=k

Answer:
135 degrees
Step-by-step explanation:
2π radians is the central angle of a full circle, so 2π radians is 360 degrees.
That means that π radians = 180 degrees.
3π/4 radians * (180 degrees)/(π radians) = 135 degrees
