Answer: 8) 42°, 65°, 115°     9) 1.5, 2
Step-by-step explanation:
8) Right off the bat I know that the measure adjacent to 157° is 
    23°. With both numbers inside the triangle combined, we get 
    65° meaning the last number is 115 because that'll add up to 180°
9) Considering the smaller triangle has half the length of the bigger triangle
    The length of the rest are half the size too.
     EF = 1.5
     DF = 2
 
        
             
        
        
        
The function that models Mason's yearly income is 42,500(1  + 0.035)^x.
Mason's income after 5 years would be $48,084.85.
<h3>What would be Mason's income after 5 years?</h3>
The function that models Mason's income is an exponential function that has the form: 
p(1 + r)^x
Where:
- r = percentage increase 
- x = number of years 
- p = present income 
42,500(1  + 0.035)^x
Income after 5 years: 42,500(1  + 0.025)^5 = $48,084.85
