Step-by-step explanation:
In the picture above.
Number 2 I suppose that as a straight line
so , it becomes easy to solve for y angle.
I hope that it's a clear solution.
Answer:
x = 50
Step-by-step explanation:
When two secants intersect in the interior of a circle, the angles formed are the average of the arc an angle and its vertical intercept. In this case, our angle, 73, should be the average of x and 96. We can translate this to an equation and solve:

x + 96 = 146
x = 50

-5 -4-11/3-3 -2 -1 0 1 2 8/3 3 4 5
8/3≈ 2,6
-11/3 ≈-3,6
If you put 5 which means its 2 1/2 ( I think) Because two 1/2 makes one.
