Write a two column proof for the reflexive property of Angel congruence

1 answer:

6 0

If you can separate the figures and the segment, or angle in question, is the same, the reflexive property of congruence can be used in the proof. ... Separating the two triangles, you can see Angle Z is the same angle for each triangle. Since they are the same angle, the angle is congruent to itself.

$\\ \sf\longmapsto \dfrac{AK}{DK}=\dfrac{CK}{BK}$

$\\ \sf\longmapsto \dfrac{14}{12}=\dfrac{4x+1}{3x+3}$

$\\ \sf\longmapsto \dfrac{7}{6}=\dfrac{4x+1}{3x+3}$

$\\ \sf\longmapsto 7(3x+3)=6(4x+1)$

$\\ \sf\longmapsto 21x+21=24x+6$

$\\ \sf\longmapsto 24x-21x=21-6$

Veseljchak [2.6K]

Answer:

C 1099

Step-by-step explanation:

The volume of a cylinder is given by

V = pi * r^2 *h

We know the radius is 5 and the height is 14

Substitute in what we know

V = 3.14 * 5^2 *14

V = 3.14 *25*14

V =1099 in^3
