Answer:
47°
Step-by-step explanation:
In the picture attached, the problem is shown.
When two secants intersect at a point, the angle made is one-half of the difference between the greater arc and the minor arc formed. In this case:
∠ABC = 1/2*(arc DE - arc AC)
Replacing with data from the picture:
∠ABC = 1/2*(142° - 48°)
∠ABC = 47°
 
        
             
        
        
        
Answer:
3.63E-5
Step-by-step explanation:
Convert 3.63 x 10^-5 from a scientific calculator
We do this by raising 10^n power * whole number entered where n=-5
3.63 x 10^-5 converted to a number = 3.63 x 1.0E-5
3.63 x 1.0E-5 converted to a number = 3.63E-5
 
        
             
        
        
        
65 percent as a fraction is 65/100  as a decimal is 0.65
        
             
        
        
        
It's  which gives 5.23 times increase in 10 years, so 523% of oryginal price
