Answer: 
Step-by-step explanation:
The measure of the third unknown arc is
.
So, 
That means legthn+lgnth +width+width
that is the perimeter formula for a rectangle or the measure around a rectangle
it can be written as (l-legnth)
perimiter=2l+2w or
p=2l+2w or
p=2(l+w)
5(0.85)t < 1.5 is 15% decay
50(1.05)t < 100 is 5% growth
150(1.50)t > 500 is 50% growth
50(1.15)t < 150 is 15% growth
1.96875
that is the correct answer
