Which is the image of abc for a 90° counterclockwise rotation about p?

The triangle DEF

Step-by-step explanation:

If we see triangle ABC then by observing then we can say BC is base, AC is perpendicular and AB is hypotenuse .

When we rotate triangle ABC counter-clock wise rotation about P then

Then base BC becomes perpendicular of triangle, AC becomes base of triangle and  hypotenuse AB remains same .

We can see this process through diagram.

Hence, the final triangle we obtain after 90° rotation is look similar as triangle DEF

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225
