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>
Answer:
Therefore, the variable expression when a=-4, b=2, c=-3, and d =4 is

Step-by-step explanation:
Evaluate:

When a=-4, b=2, c=-3, and d =4
Solution:
Substitute, a=-4, b=2, c=-3, and d =4 in above expression we get


Therefore, the variable expression when a=-4, b=2, c=-3, and d =4 is

Answer:
x > -6
Step-by-step explanation:
-2x - 4 > 8
collect like terms
-2x > 8 + 4
-2x > 12
Divide both sides by -2, we will have
x > 12/-2
x > -6
If their mean is 5, then the numbers add up to 25.
Here are a few sets that do the job:
1, 2, 3, 4, 15
10, 20, 30, 40, -75
+2, -2, +99, -99, 25
1, 5, 5, 5, 9
