X is a 90 degree angle so x equals half of 90 which is 45
X= 45
Since x is 45 the other angle on the other side is 45 
Every triangle equals 180 so you take 45+45 to get 90 and subtract that from 180 and get 90 
Y= 90

Answer:
a(b + c) = a • b + a • c
=> 8(3 + 4) = 8.3 + 8.4 = 24 + 32

It would be 125.4 . Find this by isolation the variable on the right side by using the multiplication property of equality. Multiply both sides by 57 so it would leave you with (125.4 = z). Hope this helps! :)
