Answer: 56 degrees
Step-by-step explanation:
We know that angle between b and c is 90 degrees. Because there is a line dividing angles a and b from 124 and c, we also know that each side is 180 degrees (a and b add to 180, and 124 and c add to 180).
124 and c are supplementary angles. We can represent this in an equation to solve for c:

Answer:
3).

4).
If it was by 10, k = 3 by 10
k = 30
5).

Answer:
$4000
Step-by-step explanation:

100%-30%=70%
So 2800=70%
2800/7=400
400=10%
400*10=$4000
