the length of the arc cnb is 1 by 5 of the perimeter of the circle and the length of the arc amd is 1 by 6 of the perimeter of the circle what is the measure of the central angle of the arc cnb and find the measures of angeles cdb, abd and apd

is there any attachment? what are the equations?

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down

source:

30 feet

step-by-step explanation:

that would be 2 1/2 * 12

= 24 + 6

= 30 feet   (answer)

b. is true. hope this . happy
