the sum of supplementary angles is 180 degree
therefore 
x +2x = 180°
3x = 180
X = 180/3 = 60° 
the value of X is 60° 
 
        
             
        
        
        
4x+3y=7
3x-2y=9
12x+9y=21
12x-8y=36
^^Multiply top equation by 3 and multiply bottom equation by 4 
 12x+9y=36
- 12x-8y=36
 17y=-15
^^Then subtract those two new equations
17y/17= -15/17
Y= -0.88
^^Next divide both sides by 17 
4x+3* -0.88=7
 4x + (-2.64) =7
 -(-2.64) -(-2.64)
 4x = 9.64
 4x/4=9.64/4
 X=2.41
^^then choose on equation and put your new y in the y spot and solve. 
X=2.41 
Y=-0.88
Your point/coordinate is (2.41,-.88)
        
             
        
        
        
Answer:
a= 168
p= 62
Step-by-step explanation:
25 24 and 7 are pythagorean triples. meaning the short side length is 7.
24*7 = 168
48+14=62
