Answer:
<CBD =75 degrees.
Step-by-step explanation:
I'm assuming that you want to know the value of <DBC
When a ray has the fixed end on a line, that ray will cut the line into 2 angles that total 180o.
In simpler language <ABD + <CBD = 180
DBC = 75
ABD and DBC are supplementary angles. They add to 180 degrees.
ABD + DBC = 180
105 + DBC = 180
Subtract 105 from each side
105-105 + DBC = 180-105
x=3
4x+1 = 5x-2
Bringing all like terms together,
5x-4x = 2+1
x = 3
For every $55 revenue, $3 is profit
A corporation reports profit of 600,000,000
Revenue of 11,000,000,000
Therefore comparing the revenue to profit can be calculated as follows
= 600,000,000/11,000,000,000
= 6/110
= 3/55
Hence for every $55 revenue $3 out of it is the profit
