Hello There!
The exterior angle of a triangle rule is that the exterior angle  is equal to the sum of the interior opposite angles
So essentially what I'm saying is that 
z = 29 + 39
29+39=68 therefore the measure of angle z is 68
 
        
             
        
        
        
I’m not sure about number 9. But number 10 is answer C. This is because there are two sides to a coin, so you are equally likely to land on heads as you are tails. So you take 64 and divide it by 2, and get the answer 32.
