One of the other angles is 72. Vertically opposite angles are equal.
Two angles that are side by side on this arrangement are supplementary.
That means they are to 180
x + 72 = 180
x = 180 - 72
x = 108
Answer
the for angles are
72 + 72 + 108 + 108
Answer:
It takes 75 years for the investment to quadruple in value
Step-by-step explanation:
Simple Interest
This is a simple interest problem.
The simple interest formula is given by:

In which E is the amount of interest earned, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time.
After t years, the total amount of money is:

In this question:
4% simple interest per year, so I = 0.04.
Quadruple:
t when T = 4P.
The interest earned is:



Now we find the time.





It takes 75 years for the investment to quadruple in value
Answer: It would be 4b+44
Step-by-step explanation:
This is the distributive property! so a(b+c)=ab+ac
In this case–4b+44!
That would be vertical angles if they are angle opposite each other when 2 lines intersect.
