Answer:

Step-by-step explanation:
The scale factor (C) is the ratio of corresponding parts of the two pyramids.
The ratio of the areas is the square of the scale factor.

10000x8%= $800 anually
anually=yearly
800x18=14400
What is the question that you are asking? Do you need to write an equation?
If the whole angle (ABC) is equal to 133, we can add angles ABD and DBC to find x.
10x+13=133
Subtract 13 from both sides to get
10x=120
Divide both sides by 10 to get that x=12
We can now plug the value of x into ABD to find its measure.
7(12)+4
Simplifies to 84+4, which is 88
So angle ABD is equal to 88 degrees.
