For this case we have the following equation:
From here, we must clear the value of x.
For this, we follow the following steps:
1) Place the variable on one side of the equation and the constant on the other side of the equation:
2) Make common factor x:
3) Clear the value of x:
Answer:
The relationship between x and the difference of a - b is inversely proportional.
Answer:
Step-by-step explanation:
The tangent segment is perpendicular to the diameter, so the triangle is a right triangle (not just based on its appearance). A property of circles is: a tangent is perpendicular to the radius drawn to the point of tangency.
In the right triangle, one leg has length 12.6, and the hypotenuse has length 21.
Apply the Pythagorean Theorem: (leg)^2 + (leg)^2 = (hypotenuse)^2
Oh, and the diameter has length 2x!
