Step-by-step explanation:
since the radii are all congruent, you can just draw a new one and call it KP. KP = 5 because all radii are congruent. By doing this, point P is now a tangent.
Answer:
The variable "a number" stands for 9.
Step-by-step explanation:
Rewrite the problem as 2 * (6 + x) = 30
Divide 30 into 2. 30/2 = 15
That means that the variable that is added to 6 must make the number 15.
15 - 6 = 9
The variable x is 9 so the equation would be:
2 * (6 + 9) = 30
Some sets of numbers are rational and irrational numbers.
Rational numbers are numbers you can make by dividing one integer by another.
Irrational numbers are numbers that can be written as a simple fraction.
