Answer:
Is there a rigid transformation that maps triangle ABC to triangle ABD? If so, which transformation?
yes, because a translation to the right will map ΔABC to ΔABD
yes, because a rotation about point B will map ΔABC to ΔABD
yes, because a reflection across BA will map ΔABC to ΔABD
no, because no rigid transformation will map ΔABC to ΔABD
Step-by-step explanation:
Yes it is. When you simplify the girls ratio( 12:30 by 6)you'll get 2:5. When you simplify the boys ratio( 16:40 by 8)you'll get 2:5. So it is the same ratio.
20/9 is the answer that I got
Answer:
80
Step-by-step explanation:
in the figure above, angle 100 degrees is corresponding to the angle co - interior to angle x
that is
if we put an angle that is at the upper left of x, we can call that y which is corresponding to 100 degrees
since y is corresponding to 100 degrees, it automatically becomes the same as 100 degrees
therefore y=100
now, from the first line above, we know that x and y are co-interior which means that they both add up to 180 degrees
that is
x+y=180
we know that y = 100
therefore,
x+100=180
collect like terms and
x = 180-100
therefore,
x= 80
