If the triangles ABC and A'B'C' are similar, then
angle A = angle A'
8x-10 = 6x+10
8x-6x = 10+10
2x = 20
x = 20/2
x = 10
So angle A is
angle A = 8x-10
angle A = 8*10-10
angle A = 80-10
angle A = 70
making that the measure of angle A' as well
This is why the answer is choice A
Since they all begin with 2, you need to look for the biggest number after the decimal point, since it's 4 then 2.4 is the biggest number
The answer would be 12/54 (twelve fifty fourths) but if you simplify it you would get 2/9 (two ninths).
I’m not sure what you mean but if the denominator is equal to zero, that makes the answer undefined. If the zero is at the top, the answer for that term is zero. To remember this I use zero UNDEr=UNDEfined
The answer for this problem is C
