Answer:
   a = 64, b = 90, c = 26, d = 90, e = 26, f = 120, g = 120, h = 60,
   i = 56, j = 124, k = 56
Step-by-step explanation:
Vertical angles are congruent; linear pairs are supplementary; two angles dividing a right angle are complementary. These are the angle relations you need to know to solve this.
__
Working from the top and from the given angles, ...
   h = 60°
   f = g = 180° -h = 120°
   j = 124°
   k = i = 180° -124° = 56°
   a = 64°
   b = d = 90°
   c = e = 90° -64° = 26°
In summary, measures in degrees are ...
   a = 64, b = 90, c = 26, d = 90, e = 26, f = 120, g = 120, h = 60,
   i = 56, j = 124, k = 56
 
        
             
        
        
        
Answer:
No
Step-by-step explanation:
To be a function, each input can only go to one output
0 goes to 1 and 2 so it cannot be a functions
 
        
             
        
        
        
Y=-3x-2
subsitute -3x-2 for y
-7x+3(-3x-2)=10
distribute
a(b+c)=ab+ac
3(-3x-2)=-9x-6
-7x-9x-6=10
add like terms
-16x-6=10
add 6
-16x=16
multiply -1
16x=-16
divide 16
x=-1
subsitute
y=-3x-2
y=-3(-1)-2
y=3-2
y=1
x=-1
y=1
(x,y)
(-1,1)
        
             
        
        
        
Kristin jogs 48 miles in 50 minutes, so her unit rate is 48miles/50 minutes 
        
                    
             
        
        
        
1/4 of 180 gets you the answer 45
