Answer:
x = 105
Step-by-step explanation:
the sum of all interior angles of any four-sided figure has 360 degrees
∡F and ∡H are equal
add all four expressions and set them equal to 360
x + (x + 5) +( x + 5) + (140 - x) = 360
combine like terms
2x + 150 = 360
2x = 210
x = 105

Answer:

Step-by-step explanation:
Total number of red disk=6
Total number  of yellow disk=2
Total disk=6+2=8
Odd number=1,3,5,7=4
Odd number on red disk=1,3,5=3
Probability,
Using the formula 
The probability of getting odd number disk=
The probability of getting odd numbered  red disk=
The probability of selecting a red disk,given that an odd numbered disk is selected=
Using conditional probability 

 
        
             
        
        
        
-2-3x=3+1x
-2-3=1x+3x
-5=4x
x=-1.25
