Probability of having a girl: 1/2
Probability of having another girl right after: 1/2
Probability of having a boy right after: 1/2
Then another boy: 1/2
And a third boy: 1/2
To find compound probabilities, just multiply them together.
 
 
        
        
        
the 2 angles are congruent so...
x+40=3x    set the 2 equations equal to each other
40=2x      subtract x from both sides
20=x     divide by 2
x=20 is the final answer
Have a blessed day!
