Answer:
The angle measure is 111 degrees.
Step-by-step explanation:
Opposite angles confined within a circle and a square will be equal to 180. In this case, since angle Z is equal to 69, angle x is 180.
You can use elimination
7x - 3y = 4
-10x + 3y = 2
Add both equations
-3x = 6, x = -2
Plug in -2 for x in one equation
7(-2) - 3y = 4
-14 - 3y = 4
-3y = 18, y = -6
Solution: x = -2, y = -6
Answer:
A)
Step-by-step explanation:

Following the rule of PEMDAS, we do the parentheses first, giving us:
7-2 + 2
Now, left to right!
5+2
Now just add!
