1500(1+0.04)^3 = 1687.30
1687.30(1+0.05) = 1771.67 to the nearest pound: 1772
 
        
             
        
        
        
80 = -1(80), -2(40), -4(20), -5(4), 
Total answers include: -81, 79, -42, 16, -9, and 1.
None of them add up to 6!
Are you doing polynomial equations? 
If so, you can solve it the hard way.
x^2 + 6x -80 = 0
(x^2 + 6x + 9) - 80 = 9
(x+3)^2 = 89
(x+3) = 9.43
x = 6.43
If you're not doing those then I'm afraid your question has no answer.
Hope that helps!
 
        
             
        
        
        
Answer: First option.
Step-by-step explanation:
 You can idenfity in the figure that 
 is formed by two secants that intersect outside of the given circle. 
 It is important to remember that, by definition:
  
 Knowing this, you can set up the following equation:
 
 Therefore, you must substitute values into the equation and then evaluate, in order to find the measure of the angle 
. 
 This is:
