$60 , because 20%=10%+10%, and 75 10%=7.5, 7.5+7.5=15, so 75-15=60
Answer:
300*15
Step-by-step explanation:
thats it
Answer:
The scale factor is

Step-by-step explanation:
Line segmentAB has vertices A(−3, 4) and B(1, −2) .
A dilation, centered at the origin, is applied to AB. The image has vertices
A'(-1,4/3) and B′(1/3, −2/3) .
We know the rule for dilation by scale factor of k, is

This means that;

But we know, A' has coordinates (-1,4/3)
This means that


We could also compare:
4k=4/3
Which gives
k=⅓
Answer:
Yes they are.
They are congruent because they have two equal angles and one equal side
