Determine whether the conjecture is true or false. Give a counterexample for any false conjecture.

Given: a concave polygon
Conjecture: It can be regular or irregular.
Question 20 options:

True

False; to be concave the angles cannot be congruent.

False; a concave polygon has an odd number of sides.

False; all concave polygons are regular.

1/3 + 1/5 = 8/15.

step-by-step explanation:

hope it

v = 1/3 a^2h

step-by-step explanation:

if the height is 57.7cm and the height of the slant edge is 18.2cm, then the volume is 1/3 a^2h.

(0,,,0)

step-by-step explanation:

the table of x and y values is shown in the attached pic(part of question)

we have to decide according that graph

given points are (0, 0) (–1, 0), (2, 0)

when we graph these points on graph they show an increasing line as shown in the attached pic

it is x equals 3   plese mark me really need it

step-by-step explanation:
