Two angles that have the sum of 180 degrees are supplementary angles. If you need to find angle A, you just need to subtract angle B from 180 degree to find out the degree of the particular angle. Hope I helped.
I believe the phi ratio^2 = 1 + phi ratio
phi ratio = 1.6180339
phi ratio^2 = 2.6180339
The way to work it is to make a table in Excel (or equivalent program) with the data of budget for every year.
This is how it should look:
<span><span><span>year
budget
</span>
<span>
0
265.1
</span>
<span>
1
277.5
</span>
<span>
2
288.9
</span>
<span>
3
303.0
</span>
<span>
4
311.3
</span><span> 5
320.4
</span><span> 6
334.5
</span><span> 7
351.2
</span>
<span>

368.2

Select both columns and inser a scatter plot graph (menu, insert, graph, scatterplot).
Now change the design of the graph to include the model. In this case I got y = 12.724 x + 262.92
x represents the number of year after 1990 and y represents the budget.
Now you can use the model to calcualte the budget when you know the year and to calculate the year when you know the budget.
For year 2001, x = 11 and y = 12.724 (11) + 262. 92 = 402.88 (which is 402,880)
This is the same year for which the budget exceeds 400,000. </span></span></span>
Answer:
DBE=50 degrees
ABD=140 degrees
Step-by-step explanation:
CA is a line which means that it equals 180 degrees total. Subtract the other angle measurements to find that DBE is 50 degrees. Then add the angles DBE, EBF, and FBA. Hope this helps!
