Answer:
Ummm the first on I think
Answer:
11. x = -3+√37 ≈ 3.08276
12. x = 11.2
13. x = -6 +6√5 ≈ 7.41641
Step-by-step explanation:
In each case, the relation of interest is ...
(distance to circle near) × (distance to circle far) = (distance to circle near) × (distance to circle far)
When there is only one point of intersection of the secant with the circle—because it is a tangent—then the product is the square of the length of the tangent.
11. 2(2+12) = x(x +6)
x² +6x -28 = 0
(x +3)² -37 = 0
x = -3+√37 ≈ 3.08276
12. 5(5+x) = 9(9)
5x +25 = 81
x = 56/5 = 11.2
13. x(x +12) = 12(12)
x² +12x -144 = 0
(x +6)² -180 = 0
x = -6 +√180 ≈ 7.41641

<em>Comment on this secant rule</em>
This rule turns out to apply whether the point of intersection of the secant lines is outside the circle (as in these problems) or inside the circle (as in problem 9). The product of the two distances from the point of intersection to the circle is a constant for a given pair of intersecting secants/chords.
Answer:
4.
a. base angle
b. leg
c. vertex
d. leg
e. base
f. base
5. You have 3 pairs of corresponding congruent sides, so the property that proves the triangles are congruent would be SSS.
Answer:
1. KL = 29
2. angle J = 127 degree
3. angle of K = 53 degrees
Step-by-step explanation:
SInce it is a parrallelograme, one thing that will help you is to remember that opposits are the same.
1. KL = JM since they are opposite => KL = 29
2. angle J = angle L since they are opposite => angle J = 127 degrees
3. Since we know that angle J and L are both equal to 127 degree and since the sum of the angles of a parralelogram is 360 degrees, so the sum of the angles of K and M is: 360 - 127 - 127 = 106 degrees.
Since K's and M's angles are equale => 106 / 2 = 53 degrees.
