A chord is any line that touches two ends on a circle. Line segment AC is a chord.
A tangent is a line that only touches one point on the circle. The purple line on top of the circle is a tangent line.
A radius is a line from the center to any point on the circle. The red line is a radius.
A secant is like a chord, except it is a line and keeps going. The cyan (sky blue) line is a secant line.
A point of tangency is the point that the tangent line touches. The yellow point on the purple line is the point of tangency.
A diameter is a straight line that crosses the center and two points on the circle. You can say it’s two radii put together. Line segment BD (green) is a diameter.
Hope this helps!
The square root of 445 is 21.095 so the two whole numbers could be 20 and 21
Given:
The equation is
To find:
The reason for each statement.
Solution:
We have,
Using distributive property, we get
On combine like terms, we get
Using addition property of equality, add 2x on both sides.
Using subtraction property of equality, subtract 7 from both sides.
Using division property of equality, divide both sides by 20.
Therefore, the required reasons are:
2. Distributive property
3. Combining like terms
4. Addition property of equality
5. Subtraction property of equality
