A circumscribed angle is that which is formed by the intersection of the two tangent lines in a circle. With this, we can conclude that segments AC and AB are tangent to circle O. The tangent lines forms a right angle with the radius of the circle drawn from the center of the circle to the tangent point.
By the explanation above, we can say that angles C and B are equal to 90° and that triangle ACO and triangle ABO are congruent. Which means that segment AC is equal to segment AB. Thus, the length of AB is also 4.
<em>Answer: 4 units</em>
the value of x would be 150
Answer:
its D
Step-by-step explanation:
Answer:
1. {5,-9}
2.{4}
3.{9/2}
Step-by-step explanation:
The equation 
can be solved as follows:
Then, the solutions of the equation are 
.
Now, if 
, we can solve the equation 
as follows:
So, the unique solution of this last equation is 
The last equation is 
, where 
. To solve this equation we can proceed as follows:
But, x=11/4 is not a solution of this equation. So the unique solution is x=9/2.
I guess itz B because with the rest, a number can be added to get exactly 50. Example C. y= 50x. x could be 1 which is still 50 and D. y=50-x and x could be 0 which is still 50 whiles A. y=50 remains 50
