For number 11 the third angle would be equal X as the second angle is, since the two sides next to the those angles are congruent. Then you would have to set an equation saying that 2x + 38= 180 and then you can just solve for X
        
             
        
        
        
Answer:
117.00
Step-by-step explanation:
I = prt  where i is the interest , p is the principal r is the rate and t is the time in years
2 years 6 months is 2.5 years
I = 1200 * .039* 2.5
I =117
 
        
             
        
        
        
Answer:
   4.58 miles
Step-by-step explanation:
The Pythagorean theorem is used to answer such questions. It tells you the relation between the side lengths is ...
   AC² = AB² +BC²
In miles, ...
   5² = AB² + 2² . . . . . . . fill in the given numbers
   25 -4 = AB² . . . . . . . . subtract 2²
   √21 = AB ≈ 4.58 . . . . . take the square root
The distance in miles from A to B is about 4.58.
 
        
             
        
        
        
5•3•x•x•x-5•x•x•y+5•x•y=
5x(3x^2-xy+y)
Hope this explanation helps
