Find the measures of the interior angles.

Step-by-step explanation: Sum of all internal angles of a triangle=180°

x + 68 + x-24 =180

2x+ 44=180

2x=180-44

x=68

then solve

68 -24 =44 degree angle C

68 degree angle A

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
