Answer:
144
Step-by-step explanation:
angle A + angle B = 180 (supplementary angle)
A = 4B
4b+b=180
5b=180
Divide 5 on both sides to get b=36
180-36= measure of angle A
180-36=144
 
        
             
        
        
        
The answer is b. Ordered pairs
        
             
        
        
        
Answer:
x=17/14
Step-by-step explanation:
(7/9)x+2=(5/6)
18 is the least common multiple between 9 and 6, so we can multiply each fraction by 18. 
 7           18              126
----   *    ------   =     --------    =     14
 9            1                9
14x+2=(5/6)
 5            18             90
----     *   ------    =   ---------     =     15
 6             1                6
14x+2=15
<u>      +2 +2</u>
14x=17
x=17/14
Hope this helps!
