Answer:
92
Step-by-step explanation:
<C = 180 - 140 = 40 deg
180 = 40 + 2x + (x+2)....... x= 46
<B = 2x = 2*46 = 92 deg ans

Answer:
36 : 6 and -6
 12 = 
1.96 =1.4 and -1.4
 0.64 : 0.8 and -0.8
400 : 20 and -20
 25/36 = 5/6 and -5/6
Step-by-step explanation:
we know that 
(-x)^2 = x^2 
ALSO 
(x)^2 = x^2 
thus, square of both negative and positive number is same positive number.
_________________________________________________
36 = 6*6
36 = -6*-6
hence 
square roots of 36 is both -6 and 6
12 = 4*3 =  
 

also 
12 = 

___________________________________
1.96 = 196/100 = (14/10)^2
1.96 = 196/100 = (-14/10)^2
hence 

_______________________________
0.64 = 64/100 = (8/10)^2 = 0.8^2
0.64 = 64/100 = (-8/10)^2 = (-0.8)^2
Thus, square root of  0.64 = 0.8 and -0.8
_________________________________
400 = 20^2
400 = (-20)^2

__________________________________
25/36 = (5/6)^2 
25/36 = (-5/6)^2
